    renderer: implement PlaybackStorageMedium variable
    
    PlaybackStorageMedium should be "NETWORK" when AVTransportURI
    refers to a resource received from the UPnP network. It should be
    NONE if AVTransportURI is not set.
    
    Also fix the LastChange value of PossiblePlaybackStorageMedium.
