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.
