Title: Adds support for nested scrollviews

Not sure of a more elegant way to detect perpendicular direction. Having to wait for the first change event means the final target scrollview will lose the NSEventPhaseBegan, but preliminary testing didn't cause any problems.

Tested on a magic track pad.
