Title: Conditionally disable access to private UITouch ivars (fix broken build with iOS 6 SDK)

UITouch ivars have been removed of the iOS 6 SDK headers: private API access in UIViewAdditions breaks the build on iOS 6.

The flag to activate the UITouch extensions is now more strict, so that it is not enabled by default in debug builds, and require an explicit setting.
