adjusted controls for Touch interface on iOS.

* Single Tap now implemented
* Touch and Hold (2 secs) to pop up menu
* added a pan gesture to simulate flicking up/down and left/right
* removed dependency on binding keys to game for iOS devices. (perhaps extend this to all touch devices.)
* flicking motion needs to be expanded to allow for smooth scrolling. Right now every flick is equivalent to going one slot up/down/left/right.
