Finally the trash, which was the last item that needed to be implemented as an action, is an action, a KatzeArrayAction to be exact. This simplifies more code and also makes Window and RecentlyVisited generically implementable. Incidentally this change also fixes a bug where the browser tried to add a new tab when the last one was closed, even while destroying itself. Furthermore sokoke_image_menu_item_ellipsized and sokoke_widget_popup were promoted to Katze. We're still keeping the old functions for now.
