[MERGED PR] Disables antag captains on classic

[JanusRose]

Well looks like it was called, Cap is no longer antag, but just as their are low effort Antags everywhere, there are high effort ones. The Captain being such a primary role is in the best position to do very wild gimmicks.

I've made everyone captain, started a cloning farm, paid for my own private security out of staffies etc. It'll be just a little less fun to play without that sort of chaos. And perhaps just the motivation I needed to investigate other servers for different fun.

This server has been a nice introduction to Space Station 13 though. Thanks for that, may you continue limited shenanigans.
