Improvements to chat lobbies:

- added generic methods and items for bouncing generic objects through lobbies
	- added handling of peer typing status
	- proper handling of peer join/leave lobby
	- added sub item ids to lobby messages to allow proper message splitting
	- made 2 different message splitting methods for normal chat vs. lobbies. In v0.6, we'll have to handle all messages the same way.
	- added parent id to RsChatLobbyMsgItem, to allow threaded chat.
	- added possibility to make a lobby public/private (not yet fully working)
	- added items for requesting/exchanging list of public lobbies at friends' (not yet fully working)
	- major cleaning of p3chatservice.cc

Next move:
	- gui for listing friend public lobbies, joining them, etc.
	- load/save of persistent lobbies.
	- autoremove of inactive lobbies

Warning: lobby message items of this version are incompatible with previous versions. It won't crash, but
messages will not pass through.
