Title: Implement basic HTMLElement.style support

This does not implement any notion of CSSStyleDeclaration objects that do not have an owning element; there's no actual CSS object model in play here. This does support setting and getting properties of the style attribute for HTMLElement, and tries to implement the ambiguous CSS value serialization spec.
