[MERGED PR] Disables antag captains on classic

[Ikea]

My main issue with antag cap is just that it's very boring. Its a very strong antag, but strong in ways that arent particularly interesting. Antag engineers can be very strong, but those strengths play into the unique gear of their job, thus making them interesting to deal with. Antag caps are just "Guy with AA, some of the best armor and weapon in the game". There's nothing particularly interesting there.

Im honestly not concerned about this making seccaps more common/easy or whatever. I tend to light sec cap on occasion, I've never experienced any significant pushback while doing this. Seccaps are gonna have the same level of trust even with this change coming through, which is as long as your reasonable people will generally go along with it.
