/query command no longer returns IP addresses
Private Room refactor - Distinguish hidden and secret rooms

Seperated /privateroom command into /privateroom and /hiddenroom. In
hidden rooms, mostly set by battle players, global staff maintain their
ranks within the room, but the rank is not kept in secret/private rooms
(only set by users who can create chat rooms).

Created command /whoare to allow global staff to see the hidden rooms a
user is in.
