Build fixes.

        * WebCore.vcproj/WebCore/WebCore.vcproj: Fix malformed XML.
        * platform/ResourceLoader.h: Store whether a particular job
        has received a response within the ResourceLoader object itself, since
        it's possible that we will enter the InternetReadFileExA while loop
        twice for the same job.
        * platform/ResourceLoaderInternal.h: Add private instance variable to
        store whether we've received a response.
        (WebCore::ResourceLoaderInternal::ResourceLoaderInternal):
        * platform/win/GraphicsContextWin.cpp: Fix order of preprocessor
        directives.
        * platform/win/ResourceLoaderWin.cpp: 
        (WebCore::ResourceLoader::onRequestComplete): Ask the ResourceLoader
        whether it has received a response instead of assuming it hasn't.
        (WebCore::ResourceLoader::setHasReceivedResponse): Added.
        (WebCore::ResourceLoader::hasReceivedResponse): Added.
        * platform/win/TemporaryLinkStubs.cpp: Rename setKnobProportion to
        setProportion
        (ScrollBar::setProportion):
