[CLOSED PR] Allows 3 Security Officers to revoke Armory access

[mralexs]

I don't get the reasoning this was closed? This was a use case for closing it if A) it was authed by an antag and we need to closed and B) sometimes the emergency that the armory is opened for ends, even if it is last resort. Maybe a compromise could be that there is a timer before the armory could be de-authed by secoffs?
