Fix deprecation warnings

Replace:
 - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
 - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

With:
 - (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
