network-manager-applet: do not use appindicator because it breaks the menu

Libappindicator seems to make the menu disappear completely sometimes,
which is really nasty because one cannot change any network settings
then. The menu is restored only after nm-applet is restarted,
practically only after logout + login.

Other patches are quilt refreshed to remove fuzz caused by dropping the
patches.
