Title: Match PointerEvents spec

Implemented
----

Update polyfill to the 9/7/2012 version of the [Pointer Events Specification](http://www.w3.org/Submission/2012/SUBM-pointer-events-20120907/)

Not Implemented
----

- [Extensions to the Element Interface](http://www.w3.org/Submission/2012/SUBM-pointer-events-20120907/#extensions-to-the-element-interface)
- [The touch-action CSS property](http://www.w3.org/Submission/2012/SUBM-pointer-events-20120907/#the-touch-action-css-property)
- [The pointercancel event](http://www.w3.org/Submission/2012/SUBM-pointer-events-20120907/#the-pointercancel-event)

Differences from specification
----

- [pointerType](http://www.w3.org/Submission/2012/SUBM-pointer-events-20120907/#widl-PointerEvent-pointerType) is of type string, not an enumerated constant (Issue 2 on the specification highlights the contention).

Out of scope
----

- [Compatibility Mapping with Mouse Events](http://www.w3.org/Submission/2012/SUBM-pointer-events-20120907/#compatibility-mapping-with-mouse-events) is out of scope for this polyfill, as touch events emulate mouse events as well.
