Renamed several of the server events to be predicated by "msgType". Such as "msgTypeGetRoomList", "msgTypeRoomJoin", "msgTypeSetPresence", and "msgTypeSetPresence". This is to make it easier to differentiate the message based events from the action ones.
added roomParameter as an option field for "roomJoin" messages
