Only forward touch events if CCResponder has user interaction enabled

[Ben-G]

With the current implementation touch events caused by an active touch will be forwarded to a CCResponder even if the responder sets userInteractionEnabled to NO.

Can be reproduced with the following sequence:

• Start touch
• Set userInteractionEnabledto NO
• Move touch

With the current implementation touchMoved would be called in the above example.
With the suggested change a touch event will only be forwarded if a node has userInteractionEnabled set to YES.

I think, that if the user disables touch handling while a touch is ongoing, there are two options

1. complete the touch, as the user has already accepted it (current functionality)
2. forcefully cancel touch
   I don’t think just stopping to respond to an ongoing touch, is the right way.

Yes I was thinking about cancelling the touch as well. I would be fine with solution 2). Any other opinions on option 1) vs option 2)?
