[MERGED PR] Cloning rack

[LeahTheTech]

I ran an in-game poll on the light mechanics, overall people seem to like the concept. There's an awful lot of "What?"s but I think people just kind of like clicking that option on polls.
I think we'll stick with it for now, but I'm cautious about it potentially making stealth harder for changelings for example. In theory it doesn't provide any more actual information than the old system, but that was obscured by an awful lot of people not really knowing what the flashing red screen meant.
