Room channel and rooms list

The realtime connection now carries the IMVU chats a client is in: the hub tells each proxy in a chat which
other T5DE users are there and what community products they wear (adult products only to adult accounts), on
joining and on every change. Rooms T5DE users enter are looked up on IMVU; those that are public, listed and
whose owner turned on "List my public rooms" appear on the new Rooms page, with the T5DE users in them who
show they're online. AP rooms are shown to adults only.
