This patch moves the CSS property+value storage down to a new subclass of CSSStyleDeclaration called PropertyOwningCSSStyleDeclaration. The JavaScript wrapper for CSSStyleDeclaration now calls virtual functions on the C++ object. This is preparation for supporting computed style CSSStyleDeclaration objects which won't have internal property storage, but rather an internal element pointer. :^)
