Adds the ability to ban people from ghost roles

There are some mobs you can play as now that are PRETTY ABUSABLE, and there's some players who play fine normally, but get into trouble and take things too far when you put them in special roles, SO! Rather than just flat banning those people from the server, it would be cool if we could just, ban them from playing those roles. 

This should help with that.
