EventModel? signaling changed

  • if some of the data (favourite,alarm) has changed on the event, signal 'eventHasChanged' is emitted
  • all treeViews (eg. DayView?, FavsView?, TracksView?, ...) have to listen on this signal

Only favouritiesView is 'reset' when current tab is changed in mainWindow

  • 'cause time groupings have to be recreated, since favs may have changed
  • Property mode set to 100644
