    quartz menu: add a hack for application name
    
    Add a private hack to allow the insertion of the name of the application
    into the label of menu items.
    
    If it appears in the label of any menu item, "%s" will be replaced with
    the name of the application.
    
    We will use this for the "Hide myapp", "Quit myapp" and "About myapp"
    labels typically found on Mac OS programs.
