Fix serveral <use> issues:
- When events are dispatch to a referenced element, the actual event.target
has to be set to the corresponding SVGElementInstance object
- Node::shadowAncestorNode() should _not_ return the shadowParentNode for SVG elements
This is only needed for the HTML forms concept and breaks event dispatching for SVG shadow tree elements.
- Add SVGElementInstance as possible EventTarget in bindings/js/kjs_dom.cpp
(Now event.target returns the actual SVGElementInstance object for a shadow tree element)
