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)
See merge request !61
Savegame hotfixes
Yes, this another netgame related fix! Named this "savegame hotfixes" rather than "ERCZ hotfix" or the like in advance of the fact we probably need a general branch for other $$$.sav fixes?
Anyway, fixes included in by this branch:
* ERCZ's lava falls now act as expected rather than being stuck in place for the map's duration, fixing all other known desynchronisation issues known in the map for the time being (yay)
* Changing sector tags in a map no longer causes joiners to netgames to have their SRB2 application stop responding etc
* Player names should no longer turn red in the console in gametypes outside of CTF/Team Match if a resynch occurs (not $$$.sav related, but it's related to netplay so I lumped it in anyway)
See merge request !150
Dunno who thought it was a good idea to lump tag, nexttag and firsttag together in $$$.sav, but that meant changing sector tags caused SRB2 to stop responding since it lead to the tag lists being broken
* Cleaner A_ParticleSpawn code.
* Removed several hacks with Mario blocks, and corrected a mistaken assumption with when the FOF's thinker is being applied.
* Made the flashing of T_LaserFlash even less obnoxious.
Even more slope-related fixes
What it says on the tin pretty much:
Currently included fixes:
* Pusher specials applied to FOFs did not properly account for slopes applied to the bottom plane; this probably was just a minor slipup that appeared on adding the support in the first place, I take it? (some waterfall in the last section of SUGOI's Fudge Canyon is the only place I can think of offhand where this bug is noticable)
See merge request !114
If there's any reason to bring the old system back we could make it togglable by one of the linedef flags I suppose. Not that many people would actually use it though, most likely
for some apparent reason the compiler didn't like the while loop condition edit on its own (it complained about inline failures for P_MobjReadyToTrigger for some reason), so I had to add that extra bit above the while loop... and it was happy again, huh
