Title: Double tap gesture recognizer

I've added a double tap gesture recogniser to the HUD. This can be especially useful when dealing with
cancel operations.

The HUD now exposes two properties: listenToDoubleTapGesture, which is a BOOL and doubleTapGestureBlock, which is the block that is going to be executed when the double tap gesture is hit.

I've updated the Demo as well (see mixed example to take a look at the GR in action).
