Add light color defs for more things

This commit adds custom color definitions to almost every computer that
did not already have them. It also causes cigarretes to very dimly glow.

Also contains custom colors for candles, flashlights, and the mentioned
cigarretes.

Oh, and beepsky flashes red and blue now while in hunt mode. FTW
