        Move the menu bar out of foobar-widget as a seperate
        internal applet. The default panel configuration looks
        identical to before, but if you have a menu panel in
        your saved configuration its going to be missing the
        menu bar and the window menu. I'll be removing the
        menu panel completely and adding some compatibility
        code to load an edge panel set up like a menu panel
        when it sees a menu panel in your configuration.

        * panel-menu-bar.[ch]: new internal applet identical
        to the menu bar formerly on the left of menu panel.

        * Makefile.am: add panel-menu-bar.[ch] to the build.

        * applet.[ch]:
        (applet_callback_callback), (panel_applet_load_idle_handler),
        (panel_applet_save_to_gconf): handle loading/saving the
        menu bar.

        * foobar-widget.c: (foobar_widget_class_init),
        (foobar_widget_instance_init), (foobar_widget_exists):
        Remove the old menu bar.

        * menu.c: (add_menu_bar_to_panel), (make_add_submenu):
        Add it to the menus.

        * panel-per-panel-config.schemas.in: add the menu bar
        to the left hand side of the menu panel in the default
        configuration.

        * panel.c: (drop_internal_applet): handle dnd-ing the
        menu bar.
