+ [x] privilege system for privilege groups, something like
+ in .conf: helper { kill_global, rehash, kline_local }
+ in modules: privilege_add("kill_global"), has_privilege(source_p, "kill_global") etc, should work the way dynamic cflags/umodes done
+ -- this is done kinda like this, but not really. See HasPrivilege() calls. privilege_add() was not needed ~nenolod
