    miner-fs: Set relevant rdf:types on files
    
    This way, files will be recognized as promptly as possible as being
    of the correct type, even though tracker-extract hasn't gone through
    it yet. This information could also be used in tracker-extract itself
    in order to figure out the best extractor.
