quick frontends (widgets): added widgetNew and widgetDelete listeners: - `widgetNew` is called when a brand new widget is created (not when a new instance is created if there is already an existing one) - `widgetDelete` is called when all instances of a widget (with a given widget_hash) have been deleted.
