patch v1 - feature + tests

This new patch (named 'v1') comprises previous work done by Grace (see obsolete patches), as well as a testing infrastructure for the rect-based hit test feature.

As ways to expose the functionality, the patch:

- adds a nodesFromRect method to the Document class, exposing the funcionality to the DOM. Method returns a NodeList with all nodes that intersect the given hit-tested area.
- extends hitTestResultAtPoint method of the EventHandler with an extra 'padding' parameter, defaulting to IntSize(0,0). The rect-based hit test is performed when a non-zero padding is passed in.

If padding is IntSize(0,0) or omitted, point based HitTest is performed.
