        Use the new multiscreen support for application launching
        in libgnomeui and gdk instead of the egg-screen stuff.

        * Makefile.am: don't build the egg-screen stuff
        anymore.
        * egg-screen-exec.[ch], egg-screen-help.[ch],
          egg-screen-url.[ch]: kill.

        * panel-multiscreen.[ch]: (panel_make_environment_for_screen):
        Add this - its not public in GDK.

        * launcher.c, menu.c, panel-action-button.c, panel-action-protocol.c,
          panel-recent.c, panel-run-dialog.c, panel-toplevel.c, panel-util.c:
        Replace egg-screen stuff with the functions that ended up in
        libgnomeui and gdk.
