Subject: [PATCH] fix updates in the app menu from the linkbase.

it did not remove things correctly if the linkbase removed something while the
  menu was not shown.
it sorted the wrong list.
basically it was buggy. tested now with a duplicate .desktop id in 2 places,
  and the menu shows only one copy. updating it while the menu is not shown
  correctly updates the menu.  updating it while the menu is shown also
  correclty updates the menu.
