What changed in EDuke32, build by build

C-CON changes

Animation system overhaul part 1. This allows for an unlimited number of .anm/.ivf files to be defined via duke3d.def and played back at any time with the new CON commands. Syntax is currently as follows, but may change:

Fix tdupsprite in m32script.

Questionable CON changes and optimizations. <3

Place the current loading percentage into RETURN for EVENT_DISPLAYLOADINGSCREEN.

Faster/better optimized access to game structures from C-CON.

Clean up/refactor a few gamevar related functions based on building as C++/C99 and some interesting articles I read about how GCC and Clang optimize switches. Worth a few FPS here.

Fix EVENT_ANIMATESPRITES.

Clean up some player code a bit... make bobposx/bobposy a vec2_t, make fricxv/fricyv a per-player vec2_t (TODO: CON access), promote angvel in input_t to int16_t and allow for player angle changes that result in odd numbered angles (we were effectively artificially limiting the angle to 1024 values before), fix some HUD model ID stuff that should help with the weapons in the HRP, clean up a bunch of random functions (P_FireWeapon(), P_DisplayTip(), P_DisplayAccess(), P_DisplayWeapon(), P_GetInput(), etc). Also clean up G_SetupFilenameBasedMusic() to loop through flac/ogg/mid when searching for usermap music replacements. Some of this really needs a BYTEVERSION bump, but these commits aren't for synthesis to build so we're not doing it yet. DONT_BUILD.

Aligned gamevar/gamearray allocation

Support adding custom grps to the selector in the startup window. To use this feature, create a file with a ".grpinfo" extension in your EDuke32 directory, following this template:

Move the definitions like MAXGAMEVARS out of the enums used for the gamevar flags, because it didn't really make a whole lot of sense for them to be there.

Add "ulotag" and "uhitag" to get/setactor/wall/sector, which exposes the tags unsigned, without the typecast to int16_t. This might be useful to someone.

Fix the warnings when building with C++, add MSVC C++ build support. This also changes the internal type of lotags, hitags and cstat type fields to uint16_t instead of int16_t to clean up some dubious behavior wherein the code was using a value of 32768 as a flag in these fields for certain types of things, like invisible sprites (using the value as if it was uint16_t) where it was elsewhere checking if the value was < 0 (using the value as if it was int16_t). This change may break a few specific effects if any part of the relevant code was missed when looking for areas that needed to be addressed.

Fix useractor enemystayput breakage

Add some CON defines for friendly names to pass to definegamefuncname. Now, instead of "definegamefuncname 36 something" you would "definegamefuncname GAMEFUNC_TURNAROUND something". It's just a little something to make CON files more readable.

CON access to ud.runkey_mode through get/setuserdef

Fix EVENT_CHECKTOUCHDAMAGE (the change to how events handle RETURN broke it)

Alternate implementation of EVENT_SOUND that better covers all hard coded sounds (menus, boss recognition sounds, etc)

Fix breakage of EVENT_WEAPKEYx after r2656

Addition of 3 events:

Add a couple of missed sanity checks for accessing player and sprite structure members as vars. Should fix crashes with stuff like "ifvare player[some value greater than MAXPLAYERS].kickback_pic blah"

Fix gamearray overallocation on 64-bit... was being allocated as (array size * sizeof(intptr_t)) when the struct actually contains a ptr to a block of int32_t

Patch from Hendricks266 and whatever changes happened to be in my tree. I hope they work ;)

Fix some CON compile errors I introduced in r1857
