[MERGED PR] Random gang member selection at roundstart

[Lord_earthfire]

Personally, i think it is needed for classic. but i think for RP we will loose some opportunities for gimmicks.

There are quite some gimmicks which are heavily depending on getting a whole department or special people on board. Like it's one of the ways to get an antagonistic cargonia going properly.

I could see this replacing the way it currently works in classic and going with a 50/50 split of random assignment/posters or RP. Or at least until conspirators are added back in.
