[MERGED PR] Random gang member selection at roundstart

[Lord_earthfire]

I had sone of the new gang rounds. They certainly help get the action going fast. People begin very fast to spray and start aggression.

But besides that removes a lot of gimmick and Roleplay potential. By being an opt-in antag, you were required to present something interesting to get the ball going. That falls away, which means people fall fast into the gang gameplay loop instead of gimmicks.

So, in essence, i think the change pronounces the core gameplay loop of gangs. This would be good, if we still had conspirators.
