iOS 7 / arm64

Updated Makefile and control for iOS 7 and modern architectures and procedures (like killing backboardd). Also forward-declared the private UILongPressGestureRecognizerDelegate and pngcrushed the Settings assets. Love how everything worked perfectly out of the box on iOS 7, great work!
