Change fires to a more visually-appealing red-orange color. Looks *killer*

Browse source 
Add -brighten arg to GL targets, to replace -gamma but still look nice.
"-brighten 2.5" brightens the palette by 2.5 times, to give a similar
effect to the brightness cvar, but without the dithering brightness
gives. This is a palette hack, which means it _can't_ be a cvar.
