-PK3 files are now properly loaded as files.
-PK3 lumps are still being treated the same way as WAD files. It means they're dependant on markers, if that makes any sense in the context of a ZIP file (it doesn't). I haven't worked out this part yet but I obviously intend to do so.
-I don't know if the lumps' position address is correct, we'll figure out when I fix the thing from above.
-Tweaked compression conditional to a switch-case format, looking towards adding several comrpession algorithms; haven't removed the previous "compressed" boolean yet.
-Added dynamically allocated name strings for lumps; haven't removed the previous name field.
-Added rudimentary PK3 central directory recognition; nothing is actually loaded in the end.
* Serious refactor of - and internal exposure of - what has become S_StartCaption().
* Renaming of a few existing captions.
* The prevention of access to - or writing over - sfx_None's stuff in SOC or Lua.
* The new Lua wrapper function S_StartMusicCaption(string, tics, optional player), which essentially allows custom music captions to be created. (This is best used for stuff like final lap music in SRB2 Kart or bonus time in a thokker-like game, not a comprehensive Now Playing expy. That'd be a different kettle of fish.)
Also, updated all the lock-on stuff to use P_IsLocalPlayer instead of rolling my own.
A less memetic message: On permission of Mystic, rejiggered a few things such that Race uses cv_competitionboxes, allowing the menu to be nicer.
Also:
* disabled the doomednum for ? boxes
* made A_MixUp play sfx_lose if you're in a gametype that can't use it
* Removed the all-teleporters option from cv_competitionboxes. It could just be done by tweaking the random monitor toggles, anyways.
This means setting the skybox view angle is no longer stupid, objectplace no longer breaks skyboxes, and Lua-defined skybox mobjs can actually set a Z position more easily now.
Falling rocks fix
This fixes the rock spawners' rocks not being removed if they rolled down to the ground from a slope rather than bouncing (see https://mb.srb2.org/showthread.php?t=41963)

This allows tag lists, gravity, weather, and the "CheckFor" vars to be initialised before running P_LoadThings or P_ResetDynamicSlopes, in case they could affect mobj spawning or cause a netgame desync somehow by carrying over the previous level's values
DrawFill made not stupid
made it more consistent with other drawing functions; doesn't draw off of the sides, and doesn't ignore snapping or widths for reasons that don't make sense
(for instance: the green bar in MI's test script showed *above* the blue one in non-green resolutions in 2.1.17)
