     Onionskin Configuration Dialog:
     added Close Button, Auto Create after Load, Auto Delete before Save
     (suggestions from Richard Van Den Boom),
     Scope of Onionskin Settings changed from "Global for GIMP Session"
     to "Permanent for the current Animation"
     (Settings are now stored in the *_vin.gap files)

     Some Internal Reorganisations, more general video_info file handling
     (added processing of the onionskin Settings here)

     Bugfixes Navigator Dialog: video paste now working again,
                                scale slider now reflects visible size
                                del_button, dup_button sensitvity depends on selections
