        * kjs/internal.cpp:
        (KJS::InterpreterImp::initGlobalObject): Add the built-in object
        prototype to the end of the global object's prototype chain instead of
        just blowing away its existing prototype. We need to do this because
        the window object has a meaningful prototype now.

        - Fixed <rdar://problem/4478467> document.defaultView should return 
        the window object
        
        Also made part of the window object autogenerated by IDL file.
        
        * DerivedSources.make: Added /page to IDL file search path, added

        (KJS::Window::getValueProperty):
        (KJS::Window::clear): Added call to setPrototype to ensure
        that the prototype gets cleared during navigation. (Previously
        this wasn't an issue because the window object had no real prototype.)

        * bindings/objc/DOMCSS.mm: Added NULL checks for the AbstractView
        (Presumably this is an issue after the window is closed.) Typedef-ed
        AbstractView as DOMWindow. I could have just replaced AbstractView
        with DOMWindow, but I think it's clearer to say, "There's this thing
        called the AbstractView, but really it's just the window."

        * bindings/objc/DOMViewsInternal.h:
        * bindings/scripts/CodeGeneratorJS.pm: Removed unused
        GetLegacyImplementationIncludes. Added support for DOMWindow and new
        "DoNotCache" attribute. Replaced C macros with text because (1) it
        makes the generated source easier to read and debug and (2) it made 
        it much easier to implement the DoNotCache attribute.
        * bindings/scripts/IDLParser.pm: Return a hash reference instead of
        a hash, because otherwise an interface with more than one attribute
        returns too many arguments to be processed.
