* [NUI] Add ExcludeLayouting to View

 - If ExcludeLayouting property is false, the view is not affected by parent layout
 - Even the property is false, the children Views are affected by layout of current View
 - This ExcludeLayouting property is changed synchronously with SetPositionByLayout of its layout
 - Children of AbsoluteLayout can freely be animated.
