    GtkMenuTracker: add 'special' items
    
    Allow the possibility for items to be marked with a special attribute and
    expose this via GtkTrackerMenuItem.  For internal use only.
    
    We will use this to implement the special 'Hide', 'Hide Others' and 'Show All'
    items and the 'Services' submenu in the Mac OS application menu.
