thirtyflightsofloving/ui/ui_subsystem.c
Knightmare66 26d58b1694 Added screenshot gamma correction. 
Changed stats.log to save to savegamedir instead of the Quake2 root folder.
Renamed cvars menu_sensitivity, menu_rotate, and menu_alpha to ui_sensitivity, ui_item_rotate, and ui_background_alpha.
Removed some unused cvars.
Added CVAR_SAVE_IGNORE flag to "game" and "gamedir" cvars.
Added descriptions for most cvars.
Added dumpcvars command to output a list of cvars with their descriptions to cvarlist.txt.
