TD rendering freeze fix
This is a fix for the Lava Mountain freeze issue from TD (KartKrew/TD#13) which can also occur in vanilla SRB2 as it turns out. Basically the issue occurs whenever an FOF with a single-patch texture with holes goes off the bottom of the screen far enough.
See merge request !159
This fixes the grid floors in TD's Lava Mountain freezing the game if they go off the bottom of the screen far enough (they have ACWRFL1A as the wall texture, which is a single patch texture with holes)
Still need to figure out the way to sort pressing esc on reselect level sending you back to the title screen. This will need further whittling before I can call this a solved section and move onto MP stuff.
* More comprehensive "pick up where you left off" system.
* Made individual map name selection actually take into account the map name AND the act number if the heading isn't the zone name.
* Named all the new functions/etc "Platter" instead of "NewList", to make maintenence easier and also because it sounds delicious.
* The code, as a whole, is much cleaner.
* Allows for multiple items under the same heading now, with highlights and spacing consistently handled.
* Allows for picking up where you left off between menus now (assuming the same map is available on multiple screens).
* Defined M_CanShowLevelInList in terms of the two compartmentalised functions cleaved from it, in order to ensure consistency and prevent code duplication.
* Fixing an inconsistency with being able to change skin colours when you shouldn't be able to, much like the previous skin change issue that was fixed.
Better papercollision
Diagonal bounding boxes are no longer root 2 larger than they should be. Testwad is <root>/toaster/sawb.wad. Nice and simple.

Slopewall transfer
As @Nev3r wants. Go along a slope, hit a wall? LAUNCH! Well, I mean. He wants it slightly less weak. I have already made it less weak than P_SlopeLaunch.
Also also I made the trail that goes behind the player when they're rolling take into account vertical momentum as well as horizontal, so that being launched directly up didn't leave you trailless.
Test with <root>/!LatestSRB2Files/srb2win_branch_transfer.exe and <root>/Nev3r/ACZMaster.wad (roll down slope directly in front of you).

Hardcode some stuff in patch.dta
Does what it says on the tin. I wanted to do the Christmas objects before creating the merge request, but it's advisable to block patch.dta's updating as little as possible, and I'm slowing down on my own development speed, so better move quickly.
Also, I hardcoded a nicer rolling trail aura from smiles.wad/smilespatch.wad, a nicer fire from new CEZ1, made the Koopa shell more fun and made the spinning flame jet WAY less hacky.
Check <root>/!LatestSRB2Files/ for srb2win_branch_hardcode.exe and the patch.dta fork it runs off, which includes all the necessary changes here.

Revamps of several dated linedef type effects
Felt like being productive so made some things I hate suck less.
Linedef type 7 (flat alignment) now works as follows.
* Linedef angle (from v1 to v2) is flat angle.
* Origin of flat is manipulated to match v1's coordinates - unless ML_NOKNUX is flagged, in which case uses frontside x and y offsets as flat offsets instead.
* ML_NOSONIC prevents changing floor.
* ML_NOTAILS prevents changing ceiling.
* Both of the above flags at once prints a warning.
* (THZ and probably a few other maps need updating.)
Linedef type 540 (friction) now works as follows.
* Controlled by x offset instead of length - offset of -100 is maximum iciness, offset of +483(!!!) is the maximum sludginess BUT things are scaled such that +100 is about the maximum sludginess any reasonable human being would want in a level, 0 is ORIG_FRICTION)
* Not reliant on a sector special to function (can be applied solely by tag to in-map sectors or solid FOF control sectors)
* Uses less memory, perform less calculations, and not bug out objects which just happen to use movefactor for something
* PHYSICS CHANGE: Low friction surfaces actively impede your acceleration (and make your animation speeds faster to give off that Looney Tunes out-of-control effect)
* (ACZ and Frozen Hillside needs updating.)
Sector types 1 and 3 in section 3 no longer do anything.
Linedef type 3 (zoom tube) now works as follows.
* Abs of frontside x offset is speed in units of FRACUNIT/8.
* Abs of frontside y offset is waypoint sequence number.
* Effect 4 flag rotates the player to match the waypoint direction (same as before).
* (ERZ needs updating.)
Linedef type 11 (rope hang) now works as follows.
* Abs of frontside x offset is speed in units of FRACUNIT/8.
* Abs of frontside y offset is waypoint sequence number.
* Effect 1 flag makes rope transfer one-way. (same as before)
* No climb flag makes rope static. (same as before)
* (ACZ and maybe ERZ need updating.)
Linedef type 258 (laser) is almost the same as before, but has altered functionality.
* Its flashing is less obnoxious. (56.25% to 68.75% instead of 100% to 0%, at half the speed)
Linedef type 14 (Bustable block parameters) is new, and works as follows.
* Tagged to the control sector of a block that is likely to be busted (via executor or collision, doesn't matter)
* Concatenation of frontside textures is MT_ object type to spawn, defaults to MT_ROCKCRUMBLE1 if not present
* Sound played when being busted is object type's activesound
* Frontside x offset is spacing (in fracunits) of spawned particles, defaults to 32<<FRACBITS
* Frontside y offset is the fuse of spawned particles in tics, defaults to 3*TICRATE, if set to -1 fuse is not set
* Effect 1 flag makes particles "fly out" horizontally and vertically from the center of the FOF
Sector types 7 through 15 in section 3 no longer do anything.
Linedef type 250 (Mario Block) is almost the same as before, but has new functionality and is slightly different in another way.
* No Climb flag turns it into a brick block (set on Custom FOF via presence of FF_SHATTERBOTTOM - busts when hit from the bottom, player hits their head/fist/whatever, no more upwards momentum)
* Effect 1 flag makes it an invisible block (set on Custom FOF via absence of (FF_SOLID|FF_RENDERALL|FF_CUTLEVEL) - intangible from every side except the bottom. Becomes visible and tangible when it's hit once)
* Only updates side textures when moving down or stationary, not whilst moving up - more fidelity to the source material, less processing on the CPU, everyone wins.
* If FOF master linedef has a backside, then: [If there's items in it the FOF's flats are set to that of the backside sector's ceiling, otherwise the floor.] Otherwise, no flat change.
Linedef type 4 (Speed Pad parameters) now works as follows.
* Frontside x offset is speed in fracunits.
* Effect 4 flag doesn't center the player. (same as before)
* Effect 5 flag sends them off in rolling frames.
* Frontside upper texture is sound to play on launch, defaults to sfx_spdpad when not given
Sector type 6 in section 3 no longer does anything.
Object type 757 is changed as follows, and no longer works on its own - see Linedef type 15 for more details.
* Tag via its angle field
* Number of objects to spawn per tic around it via its z field, if zero then just spawn at center
* Is flipped if given MTF_OBJECTFLIP.
* (ERZ and Seraphic Skylands - if we use that map - needs updating)
Linedef type 15 (Fan particle spawner parameters) is new, and works as follows.
* Tag is tag of object(s!)
* Object type set via concatenation of frontside textures, MT_PARTICLE is default
* The length of the linedef is the radius the particle is spawned out (zeroed if z field is 0)
* Frontside x offset is speed upwards
* Frontside y offset is number of degrees to turn each tic (zeroed if z field is 0)
* Frontside floor and ceiling heights are the heights in which the particle is bound through some fun mathematics
A_ParticleSpawn is changed, too.
* Object type is now changed through actor->threshold instead of var1 to support Linedef type 15.
Test executable uploaded at /toaster/srb2win_branch_flatalignment.exe on the ftp.
Test file uploaded at /toaster/flatalignment.wad on the ftp.
Breaks compatibility with 2.1 so put in internal.

Plane displacement
Basic support for plane displacement, no netplay support as of writing but this is what Nev3r wanted moreorless at least.
Linedef types 66-68 are the plane displacement specials; 66 = move floor only, 67 = move ceiling only, 68 = both
Front sector = control sector
Tag = tag of target sectors to be moved whenever the control sector floor moves
Linedef length = movement factor relative to control sector movement, 256 = 1:1 with control sector. 128 is half as much, 512 is twice as much, etc.
Whenever the control sector floor moves (not ceiling, never ceiling), the selected planes of the tagged sectors all move (mind, they have a tic delay due to how it all works, it's not perfect really). No support for reverse speeds yet sorry.
EDIT: oh, btw, test exe and test map are included in my folder on the FTP (srb2win-plane-displacement.exe and plane-disp-test.wad, respectively)

* Made the name of P_PrepareSlopeToWallTransfer (now P_GetWallTransferMomz) make sense.
* Bugfixed the case where you couldn't reliably guess the angle of the wall you just hit.
* Seriously reworked a lot of stuff behind the scenes, thanks to Red's comments.
* More consistent behaviour.
* Launching power is now scaled to the slope's angle relative to the wall you hit, so no massive launches when you hit the side of a steep slope.
* The code is a lot messier and the function name doesn't make any sense any more, so I need to clean that up in the morning.
* Need to figure out how to prevent tiny launches that uncurl you when spindashing up against walls.
* Spindashing trails now takes into account vertical momentum as well as horizontal - it was stupid not seeing your spintrail just because you weren't moving very fast horizontally!
No exe uploaded because it's almost 2am.
GFZ3 Unfuckening
Some tweaks to the GFZ3 Eggmobile's behaviour to make it less frustrating for old and new players alike.
* GFZ3 Eggmobile's laser won't change its angle when you move left and right anymore.
* Changed because its ability to move quickly was extremely punishing for new players (see ProJared's youtube video on the matter).
* http://gfycat.com/PassionateUnknownAgama (the twitching on the third laser has been fixed since this was recorded)
* GFZ3 Eggmobile will, when too far away from the ground and moving upwards, slow itself down vertically.
* This was punishing and annoying for both old and new players alike.
* http://gfycat.com/CornyLeftDungbeetle (old values - the typical settling height is slightly lower now)

No more double-decker Detons
Oversight of a tiny hack when working on the flickies branch meant detons released twin flickies when hitting stuff. As cute as that is, it's also pretty weird.
See merge request !62
This new function returns a string representing the type of userdata the variable given (e.g. mobj_t, player_t), it even works on "minor" userdata types (player_t.powers, skin_t.soundsid, sector_t.lines, etc)
* Value was getting populated even when it was irrelevant. That's fine, just move it after the valueless parsemode switch.
* Oh, it's struppr'd, of course it's going to compare badly with a lowercase string.
* ...oh, strncmp returns zero when it's equal, not true. Right.
<root>/toaster/smilespatch.wad and !LSF test exe updated on the FTP, btw.
* Create a normal skin, but replace the S_SKIN lump with an almost empty one named P_SKIN.
* Provide "name = existing skin name as one of the first line (comments allowed)
* Reset individual spritenames back to zero sprite2s (or one for SPR2_STND to prevent complete removal) via "reset = SPR2_****" statements.
* No support for changing skin properties that are non-visual at the moment, but I don't really feel like it's wise to have those changable with patch alone. (Hello, tons of "modern Sonic" wadfiles which just change vanilla Sonic's ability to CA_HOMINGTHOK!)
* Sprites patch over.
To see an example in action, look at <root>/toaster/smilespatch.wad.
