Enhanced Movie Center 4.0

    - fix for new changes @Fischreiher
    I told you before don't break compatibility to mainline Enigma2 /
    DreamOS!!!
    - Improved my last commit, muting of miniTV
    - add webm container video file extention
    - New optional method of hiding miniTV: "single pixel TV, muted"
    Workaround for movie aspect ratio issues on Gigablue Quad:
    Some movies play correctly then live TV is active before playing them,
    so do not disable the miniTV by stopping the service but use the new option.
    - changed callback value
    - [MovieSelection] reopen the movie list from a played movie from 'latest recordings' with same path
    e.g.
    - play movie from 'latest recordings' and reopen the movie list
    - folder is now also 'latest recordings' and not the real path from the movie was played
    - set new movie path only, when current path not in list or he has changed
    - removed blue button translations, (translation breaks function of the button
    - Update de.po
