- bridge methods/signals now all start with "muc" to follow new convention
- internal method use client instead of profile to follow new convention
- removed excetpions from plugin XEP-0045 in favor of core.exceptions, NotReady added
- cleaned/simplified several part of the code. checkClient removed as it is not needed anymore
- self.clients map removed, muc data are now stored directly in client
- getRoomEntityNick and getRoomNicksOfUsers are removed as they don't look sane.
/!\ This break all room game plugins for the moment
- use of uuid4 instead of uuid1 for getUniqueName, as host ID and current time are used for uuid1
