As it stands, oper hiding is rather messy and inconsistent. Add SeesOper(target, source), which is true iff target should appear as an oper to source. If I haven't missed something, all commands that reveal oper status now use the same logic. general::hide_opers_in_whois is a special case, and affects /whois only. general::hide_opers is introduced, and has the same effect as giving everyone oper:hidden. All commands that reveal oper status respect both.
