plugin XEP-0045, quick_frontend + primitivus (chat): cleaning of XEP-0045 (first pass):

- 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
