Adding support to restore widgets even for jelly beans.

> Show 'widget-not-ready' until the widget app is installed
> Once the app is installed, bind a new widget id (not required on L if
  id-remap was received).
  **Remove the widget if bind failed
> If the widget has no configuration screen, show the widget, otherwise
  show 'setup-widget'.
> Clicking 'setup-widget' shows the config screen, and updates the
  widget on RESULT_OK.
