- fixed indices when deleting and inserting items, so we can update   the menus correctly, not only construct them in the right order. - install an emission hook on the "parent-set" and update the menus   accordingly when it was a GtkMenuItem of the global menubar   that was added or removed. - added some conditional debugging output, i'm sure we will need   it again ;-)
