Pass the prototype of WebCore JS objects up the constructor chain
        rather than explicitly setting using setPrototype.  This removes many
        redundant settings of the prototype on construction.  To avoid a CG 
        hazard, the prototype must be constructed before before calling the
        constructor of the JS object.

        - JS objects that inherit from DOMObject, which all bindings objects
          (except Window) do, now can't implicitly have a jsNull prototype, but
          must explicitly pass it up the construction chain.
