Refactor synthetic gesture handling to prepare for more gestures.

Currently there's only one gesture, smooth scroll. This patch provides
changes that will make it easier to add new gestures. Functionality
that's independent of scrolling has been renamed to SyntheticGesture*.

Since many touch gestures are variations of touch-drag (with one or
more pointers) this patch introduces a new GenericTouchGesture Java
class to simulate all of these gestures. Currently, it only supports a
single pointer, but it can be easily extented to support more. The
smooth scroll gesture uses this class for the Android implementation.
