Message:

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
