        * panel-recent.[ch]: (panel_recent_append_documents_menu):
        Re-work so that it returns the newly created EggRecentViewGtk
        and allows it to be re-used by passing it back in as a parameter.

        * panel-menu-items.c:
        (panel_place_menu_item_create_menu): hold a ref on the
        EggRecentViewGtk and re-user when re-creating the menu.
        (panel_place_menu_item_finalize): unref the view.

        * egg-recent-view-gtk.c:
        (egg_recent_view_gtk_clear),
        (egg_recent_view_gtk_set_list): don't barf if view->menu is NULL.
        (egg_recent_view_gtk_finalize): don't unref the menu.
        (egg_recent_view_gtk_set_menu): don't take a ref on the menu.
        There's no point in us updating a menu which has been destroyed.
