In the API, a firm distinction between initially fetching a room's
metadata and receiving further changes has been made:
IM_ROOM_METADATA will be sent to Caya on request (IM_GET_ROOM_METADATA)
with the room's name, subject, etc. The other metadata-related messages
should only be sent to Caya after the room is initialized, not as a
means of initially setting its metadata.
Basic room flags were added, though they aren't yet used― they should
allow the protocol/add-on/user to configure some room features. Logging,
auto-joining, etc.
