[CLOSED PR] Reintroduces antag captains on RP

[Ikea]

Captain has no set job, the only special mechanics they get are combat/loot obtaining oriented (things like better armor, a gun, aa, etc). This means that antag captains will tend to do gameplay strategies that use there special mechanics, which is things like getting stacked with items and focusing on combat instead of social stuff. Of course, this doesn't mean that roleplay captains will just do a powergame rampage, they still tend to respect roleplay rules. What this does mean however, is that the vast majority of times, antag captains play as "good luck catching me with my aa implant and 4 aa ids hidden across the station" and rarely something else (this applies to classic antag cap as well, but outside of scope). I dont see any reason for this playstyle to go away when it gets reintroduced.
