fteqw/engine/gl/gl_alias.c
Shpoike 7e9d138d5f Try to fix up some q2 protocol/ice quirks. 
Add r_imagelist_wad command to show lumps in the current map's wad list.
Hide the gpu utilisation info unless developer. its misleading on account of power profiles.
Make the menu not flash/animate so much when something else has focus.
Add QTV streaming option when browsing servers (assuming servers are configured properly).
Show people's health+armour+weapons on the scoreboard, if we have that information.
"enemyskin solid; enemycolor 0x00ff00" will make enemies full green without needing any external texture files.
Add ENGINE_HAS_ZIP build option, to have the engine look for concated(self-extracter style) zips for use in single-file games.
Small speedup for hl2bsp load times.
ftemaster now supports bad-word filters. Basic, probably easy enough to hack around, but at least we tried, admins can extra words as needed. People should at least realise they're being naughty.
Misc fixes for ftemaster's html generation.
Add support for a couple of quirky hlbsps.
Don't attempt to auto-use setangles_delta when sv_nqplayerphysics is active, to avoid compat quirks with AD.

//a note about dedicated servers:
//In the server-side gamecode, a couple of q1 extensions require knowing something about models.
//So we load models serverside, if required.
//things we need:
//tag/bone names and indexes so we can have reasonable modding with tags. :)
//tag/bone positions so we can shoot from the actual gun or other funky stuff
//vertex positions so we can trace against the mesh rather than the bbox.
//we use the gl renderer's model code because it supports more sorts of models than the sw renderer. Sad but true.
