Fast same button press

[ageorgios]

When you press the same button more than once, you need to wait before the animation finishes to press again.
(Gesture: Failed to receive system gesture state notification before next touch)
This leads to slow entering of common passwords like 0000, 1111 and likewise

Maybe it could be fixed by adding the selected view after the buttonview in the self.view hierarchy

[ChocoChipset]

Fixed this by enabling the flag UIViewAnimationOptionAllowUserInteraction on the UIView's animation.
Waiting for review,@abury.
