Spoike fdd903e0a3 win: emulate gamepad thumb axis as buttons. 
keys: add some extra key names for compat with DP+QS (primarily gamepad buttons).
keys: fix a few keys getting mistranslated between engine and qc scancodes.
engine menus: remove 16bpp from the video options menu on win8+, as win8 no longer supports anything but rgbx8.
pmove: coord size and rounding is now part of the pmove code itself. this fixes truncation issues.
r_clutter_density: fix crash from clutter comprising of boneless iqms.
gl: added cvars to disable immutable buffers or textures. hopefully these might be usable to work around the issue reported on various geforce 1080s
wav: convert ieee wav files to 16bit on load, in case someone tries giving us one of these.
vid_srgb: this cvar now uses -1 for the former gamma-only setting.
r_viewmodel_quake: new cvar (name comes from quakespasm) that can be used to disable the weird movement of the viewmodel when pitching up or down.
nquake: try to block nquake's frogbot's autoexec.cfg, as I keep getting complaints about it fucking over singleplayer games.
fs: added -netquake commandline argument that disables the use of the qw/ gamedir.
fog: disabled fog on aky surfaces, as it was bugging out in The Wastes.
vid: fix some vid_restart/vid_reload issues (which got much worse recently in my attempt to fix a different crash)
routing: first attempt at engine-side routing. feature is currently disabled.
