macosx: stop the playback on when closing the main window only if there's a video inside (close #6144)

macosx: resizing fixes for the minimized state. additionally, make sure we restore the state last present on quit. (close #6122)

macosx: work-around so we don't block the main thread for ages during launch time without showing a window

This fixes a bug reported on the forum at

Note that CDDA module still needs to query freedb service for disc ID,
only the track information is cached.
