Replace Spy with Gang in Secret Rotation

[KikiMofo]

Yeah the only thing I have against gang mode is that heads can't join gangs so they end up trying their best to end the round as fast as possible like giving the AI a law to screw with gangs and making bombs and shit like that. I assume that is one of the reasons it needs to be watched by admins. Also I assume it needs to be watched by admins so the gangs don't go around randomly killing people that aren't in gangs.
