[MERGED PR] Disables antag captains on classic

[JOELED]

I like this change. Besides, cap doesn't have mindhack protection, they can still be mindhacked if you really want evil cap stuff to happen. I've seen several cap antag rampages lately where the person afterwards said it was boring because you start out with such an advantage, and it's lame to fight against as sec too from what I've seen. Other antags have to actually get their gear and plan around it while cap literally just spawns in and can often win against sec right from the jump
