Cmake: Add FTE_WERROR option, defaults to true in debug builds and off in release builds (in case future compilers have issues).
Cmake: Pull in libXscreensaver so we don't get interrupted by screensavers when playing demos.
Make: Added `make webcl-rel` for a web build without server bloat (eg for sites focused on demo playback. Yes, this means you XantoM).
fteqcc: Include the decompiler in fteqcc (non-gui) builds ('-d' arg).
fteqcc: Decompiler can now mostly handle hexen2 mods without any unknown opcodes.
Allow ezHud and OpenSSL to be compiled as in-engine plugins, potentially for web and windows ports respectively.
Web: Fix support for ogg vorbis. Add support for voip.
Web: Added basic support for WebXR.
QTV: Don't try seeking on unseekable qtv streams. Don't spam when developer 1 is set.
QTV: add support for some eztv extensions.
MVD: added hack to use ktx's vweps in mvd where mvdsv doesn't bother to record the info.
qwfwd: hack around a hack in qwfwd, allowing it to work again.
recording: favour qwd in single player, instead of mvd.
Protocol: reduce client memory used for precache names. Bump maximum precache counts - some people are just abusive, yes you Orl.
hexen2: add enough clientside protocol compat to play the demo included with h2mp. lacks effects.
in_xflip: restored this setting.
fs_hidesyspaths: new cvar, defaults to enabled so you won't find your username or whatever turning up in screenshots or the like. change it to 0 before debuging stuff eg via 'path'.
gl_overbright_models: Added cvar to match QS.
netchan: Added MTU determination, we'll no longer fail to connect when routers stupidly drop icmp packets.
Win: try a few other versions of xinput too.
CSQC: Added a CSQC_GenerateMaterial function, to give the csqc a chance to generate custom materials.
MenuQC: Added support for the skeletal objects API.
Defaults to using Q2E's protocol 2023 (but not netchan).
FTEQ2 servers can host both vanilla and Q2E clients simultaneously, but its recommend to use the vanilla gamecode to avoid localisation issues.
Also .bsp vs .bsp.gz etc maps are now ordered consistently too.
Modifiers like maps/foo#bar.ent are now shown separately in the listing too.
Hide maps that are shadowed by a higher-priority gamedir (so no dupes).
Closes https://github.com/fte-team/fteqw/issues/171
* Quake II: read the skin, effects, renderfx, and solidsize fields as unsigned shorts.
* Add missing header definition for int MSG_ReadUShort();
* Rename MSG_ReadUShort() to MSG_ReadUInt16() as per @Shpoike's wishes
* solidsize needs to be read in via MSG_ReadSize16 because it does protocol conversions (@Shpoike)
* Q2UFRAME16 and Q2USOUND should be read unsigned as well, as it matches the internal data within FTE (@Shpoike)
