    DocumentsUI: google please cleanup your translations....DocumentsUI cleanup

    it is really at the moment a nightmare to see compile errors when
    getting 100000 of warnings. Whatever we removed already on some
    packages the warnings....but still a lot are there

    this package is the best.......nearly every language has left
    overs where not one string is used at all and one string

    whatever remove and add it like it should

    we are now warning free
