fix for moredip/Frank#278

Per https://groups.google.com/forum/#!topic/frank-discuss/6eZ2uXIuV9A, it appears that iOS 8
changed the way coordinate spaces work for UIScreen. That mean that tap coords for landscape orientation
wasn't being mapped properly. This fixes that issue by using UICoordinateSpace if available (iOS 8 and up).
