    nepomuk: Replace tracker:Volume with tracker:IndexedFolder
    
    This class will represent all indexed folders, mount points or not.
    The tracker:available and tracker:isMounted properties are now a
    single tracker:available property set on the nie:DataSource (like
    tracker:unmounted previously).
    
    Files won't be "available" themselves, users should update to poking
    the availability of the nie:dataSource.
