-> Enabled partial updates to app widgets through AppWidgetManager.
Partial updates are not cached by the AppWidgetService.
-> Added the ability to insert commands with no parameters into
RemoteViews objects.
-> Added showNext() and showPrevious() methods to RemoteViews.
-> Made showNext() / showPrevious() of AdapterViewFlipper remotable.
