Use new per-widget editing control on MiniWidgetBar

With this new approach, we are able to remove mini-widgets from the `MiniWidgetBar` in an intuitive and transparent way.

The user can basically drag mini-widgets out of the container while in edit-mode, instead of having to get out of edit-mode and click on the widget edit button.
