    AppChooser: Respect setting of gtk-dialogs-use-header
    
    Use a header-bar for the start-up application chooser dialog if
    ‘gtk-dialogs-use-header’ is True. Rename the ‘Add Application’ button to
    ‘Add’ and add a mnemonic for it as well as changing the response of the
    ‘Close’ button so that it is placed on the opposite side of the
    header-bar to the ‘Add’ button.
