[MERGED PR] Disables antag captains on classic

[mralexs]

Another point is since now that cap is supposed to be trusted and sec lite, they should have the round minimum like playing sec does. I really don't like the cap being Green secoff instead of green staffie, even as a HoS player.

Also when Cap goes antag they can EASILY be found and shut down since unlike a lot of roles, a captain is probably not gonna abandon their starting gear, making hunt down the captain "just find the guy in green."
