Subject: [PATCH] Fixed issue in iOS devices that would cause all touch events
 to fail after a Multitasking Gesture was triggered. The fix works by aborting
 all touch contacts after a touch has been cancelled, since the Multitasking
 Gestures in iOS trigger the TouchCancel event on those touches which were
 active..
