[rhythmbox] audioscrobbler: update profile periodically

    audioscrobbler: update profile periodically
    
    When source is activated, update profile and register a timeout callback
    which every 5 minutes will update the profile. When source is deactivated
    remove the callback.
    
    Of course, these will only actually send update requests if the cached
    responses are no longer valid.
