Spr2 freeslots
Needed for Miles, generally a good idea to have around anyway. Considering Miles uses it without problems, seems to work fine.

* When moving slowly, P_InstaThrust at S_SKIN's maxdash forward, and set momz to S_SKIN's mindash upwards. Plays a tok noise (not thok). Hurts enemies/bosses, busts spikes/monitors/all types of bustable blocks.
* When moving quickly... doesn't do anything yet, but WILL do a slide.
Also, P_DoSpinDash is now renamed to P_DoSpinAbility, and CA_TWINSPIN users can bust all bustable blocks on collision too.
Setup:
* S_SKIN needs an "availability" line. Set to 0 to have always available, otherwise is assumed to be UINT8 unlockable number. If it's a valid unlockable, its name will be copied over with the character's realname.
* Define an unlockable via SOC or hardcode. If you don't want it visible on the Secrets menu, just set its type to None. Everything else is as normal - you can set the conditionset to whatever, objective, height, nochecklist, nocecho...
* radius - sets the player's radius for that skin.
* height - sets the player's normal height for that skin.
* spinheight - sets the player's spinheight for that skin.
* shieldscale - see http://i.imgur.com/BQ5DhKC.png for justification
R_SkinUnlock defines the circumstances under which a skin is available. For simplicty's sake, I've currently bound it to an S_SKIN variable so I can toggle it easily, but it WILL be replaced with a hook into the savegame system at some point.
* Currently has three tiers of unlock - freebie (forceskin or modeattacking via a loaded replay), Ringslinger Only, and SP/Coop and Ringslinger.
* I don't know anything about netcode so I basically decided to make R_SkinUnlock relevant only under local circumstances, try as hard as possible to stop bad skin info from getting sent to the server, and then admit defeat once the server has the information. If this is a bad choice, please discipline me and show me how to fix it.
* Character Select now checks for whether the character is hidden or not on menu load and does/undoes it based on that info, but will never touch one disabled via SOC. I also used this opportunity to optimise, checking for/filling out charsel pictures instead of doing it later. (It now also includes special casing for a select screen with zero characters!)
* Mode Attack now hides hidden characters in its character select based on SP rules.
Things that still need to be done:
* ForceSkin_OnChange. Is there a graceful way to handle this?
* No obvious skin name conflicts. Add a salt to the names of hidden skins, and then remove it when they're unhidden?
* The gap between Knuckles' skin number and the first custom character anybody adds will be way too obvious. A seperate hidden skin numbering system? Start at 32 and count up from there? There's a few ways...
Note: polyobj_t's "translucency" is apparently a SIGNED integer, so in theory it's possible to get polyobj flats to use the "spanfunc = splatfunc" line using negative values. If this is not meant to happen, this should probably be fixed asap

more detailed description: vissprites now store dispoffset in a separate variable from (y)scale, and uses it to influence order between sprites without it affecting the actual drawing of the sprites themselves
Monster's miscellaneous meddling
A miscellaneous assortment of code-cleanup and other changes, plus fixing up SRB2's tangent array so it behaves more as expected (especially on the Lua side).
More specific details of the changes:
(MUST-HAVE CHANGES)
* `finetangent[]` has been entirely redone in the same manner as finesine/finecosine.
* Lua's tan() function shifts `finetangent[]` results by `ANGLE_90` to get what you EXPECT it to return (e.g. `tan(0)` actually returns 0 now). This means finetangent itself doesn't need to change its general arrangment, this only affects Lua specifically.
* Lua's tan() function now also doesn't go out of `finetangent[]`'s bounds at all. Before, `tan(ANGLE_180)` through `tan(ANGLE_MAX)` and such would just give you values unrelated to the array in question, which was clearly a bad thing.
(CAN PROBABLY LIVE WITHOUT?)
* `finecosine`'s definition moved from r_main.c to tables.c.
* Created `P_CheckTimeLimit` for `cv_timelimit`, much like `cv_pointlimit` has `P_CheckPointLimit`. It cleans up `P_UpdateSpecials` a bit at least.
* Some code cleanup relating to translucency maps - these are kind of unimportant, I was about to stop `FF_TRANSMASK` being used everywhere, but this was apparently a bad idea so I backtracked a bit.
* Re-added `_MSC_VER` check around MSVC-specific code in doomtype.h, in case it wasn't defined (and `__OS2__` was). Also left a comment there regarding `__BYTEBOOL__`.
* Fixed an apparent copy+paste goofup in `joyaxis_cons_t[]` for the Wii-specific code.
