[MERGED PR] Disables antag captains on classic

[cheekybrdy]

Against myself, I like the captain being as disassociated from sec when its populated as much as possible, I feel like captain's loud atmosphere even as the only sole Command member gives Command as a department a unique character which being security conditioned with a 'All clear' would remove that by moving captain into effectively Secoff with AA (batong sold seperatly). Also as in regards to mind hacked captains I feel are just as dangerous as Traitor captains in most scenarios. The power of AA also gives a method to setup good gimmicks earlier in the round due to less wrangling of resources, although this can allow for the low effort rampages that caused this thread.

TLDR: Captains being able to be traitors gives Command as a department a unique identity and feels like a unique part of Goon compared to other codebases imo.
