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.
