    filediff: Handle save responses better in delete events (bgo#744081)
    
    The "you have modified files" dialog offers a "Close without saving"
    option, which returns a CLOSE response code instead of our usual OK.
    This was being handled correctly in most places, but not when the tab
    was being closed via a delete event. This patch fixes it so that the
    check_save_modified() always returns either OK or CANCEL, since that's
    really the only thing we need out of it.
    
    This commit also removes a stray delete-event handler on a widget that
    should never ever be loaded.
