CKViewController : Adds navigationControllerTransparencyInsets that compute the insets that should be applied to subviews if we want to layout subviews beside the parent navigation controller navbar and/ore status bar. This takes care of transparency and the os version.
CKTableView : Insets are now computed correctly so that if a tableview is in a splitter or as modal in a navigation controller, the insets are properly applied and the search bar is properly placed beside the nag bar.
CKSplitViewController : adds automaticallyAdjustInsetsToMatchNavigationControllerTransparency that ensure that the sub view controllers will be layouted beside the nag bar in all os versions and transparency conditions. This is false by default as we can want to layout table view controllers and let it scroll beside the navbar.
