fteqw/engine/client/cl_cam.c
Spoike 9033f7b237 fixed eztv md4 incompatibility. 
reimplemented qtvreverse command.
fixed some stuffcmds being handled by the wrong splitscreen seats (was noticable in TF).
rework smartjump to try to be more predictable...
rework relighting to try to be more robust (and more self-contained).
allow the csqc to actually use VF_PROJECTIONOFFSET.
jump now moves upwards instead of trying to lock on to a nearby player when spectating.
assume 32 fullbright pixels when running with a palette.lmp yet no colormap.lmp (happens with some total conversions).
tweaked scoreboard for fainter backgrounds.
rearranged autoid, to be smaller etc.
hacked around dodgy conchars.lmp - don't treat 128*128 qpics as qpics to work around workarounds for buggy wad tools (with a warning).
fixed missing fullbrights on h2holey models.
avoided warning about mod_h2holey_bugged on dedicated servers.
added net_ice_exchangeprivateips, for people worried about exposing lan IPs when using ICE.
sv_public 2: implemented client support for our webrtc broker in order to use our own ICE implementation without needing to faff around with irc accounts or plugins etc.
TODO: ensure at least one ephemerial udp port when using ice or come up with some better sv_port handling
fixed multiple tls bugs (one could cause server problems). change net_enable_tls to disabled by default anyway (reenable for the server to be able to respond to https/wss/tls schemes again).
don't colourmap when there appears to be a highres diffusemap on q1 models.
imgtool now understands exporting from qpics in wads, as well as just mips.
implemented speed-o-meter in ezhud.
added removeinstant builtin to avoid the half-second rule.
