Die notifyAttributeChange, long live attributeChanged!

Using a novel approach for handling SVG DOM dynamic updates, I found a way to
eliminate the notifyAttributeChange sledgehammer. SVG Animated properties know
it's corresponding attribute (SVGNames::foobarAttr) already, so it's easy to
call element->attributeChanged(..myCorrespondingAttribute) from the JS
bindings. I don't want to go into detail how non-animated properties are
handled - just want to outline the general idea.

All SVG elements need a proper svgAttributeChanged / childrenChanged
implementation now - instead of implementing nAC() - which blindly updated.
Gives an amazing performance boost when running layout tests or trying heavy
web apps like Lively Kernel.

Uploading insanely big patch soon.
