The room directory window now has an accounts menu, to allow the user to
filter rooms by account― and a "category" column has been added, which can
optionally be filled by the protocol for more semantic sorting of rooms
(Through "category" slot of IM_ROOM_DIRECTORY).
This window (Chat→Room directory) is to be used for either a list of
publicly available rooms (in most protocols), or for a list of
joined-but-hidden rooms (as it'll used with libpurple, to list its
ChatBuddies).
Each room is sent individually from protocols using IM_ROOM_DIRECTORY
messages sent in response to a IM_GET_ROOM_DIRECTORY message.
