        - work toward removing Objective-C data types from FrameLoader.h:
          removed NSDate, NSString, WebCorePageState, WebCoreResourceLoader,
          and WebCoreResourceHandle
        - moved bodyBackgroundColor function from Frame to WebFrame in WebKit

        * page/PageState.h:
        * page/PageState.cpp: Added, C++ class with much of what WebCorePageState had.

        * bridge/mac/FrameMac.h: Removed uneeeded declarations and bodyBackgroundColor().
        * bridge/mac/FrameMac.mm: (WebCore::FrameMac::startRedirectionTimer): Use a
        double for the date instead of an NSDate.

        * bridge/mac/WebCoreFrameBridge.h:
        * bridge/mac/WebCoreFrameBridge.mm: Removed invalidatePageCache and
        saveDocumentToPageCache methods.

        * bridge/mac/WebCorePageState.h:
        * bridge/mac/WebCorePageState.mm: Removed most of the class and turned it into
        an Objective-C wrapper for PageState.

        * loader/FrameLoader.h: Removed unused Objective-C types, eliminated use of
        NSDate and WebCorePageState.
        * loader/FrameLoaderClient.h: Changed NSDate to double.
        * loader/mac/FrameLoaderMac.mm:
        (WebCore::FrameLoader::receivedMainResourceError): Moved call to setInPageCache
        here that used to be in invalidateCurrentItemPageCache on the WebKit side.
        (WebCore::FrameLoader::clientRedirected): Changed NSDate to double for date.
        (WebCore::FrameLoader::open): Moved one of the open functions that was part of
        commitProvisionalLoad inside the commitProvisionalLoad function, so that it can
        extract the parameters from the response. Changed the open function that takes
        a PageState to use the new C++ PageState.
        (WebCore::FrameLoader::commitProvisionalLoad): Added the code from the open
        function; tightened up logic, removing a few cases that could never happen, as
        well as the unused reload boolean.

        * ForwardingHeaders/kjs/property_map.h: Added.

        * WebCore.exp: Updated.
        * WebCore.xcodeproj/project.pbxproj: Updated.

        formerly in invalidatePageCache: on the bridge here.
        (WebFrameLoaderClient::dispatchWillPerformClientRedirect): Added code to make the
        NSDate here.
        (WebFrameLoaderClient::createPageCache): Restructured code to create the
        WebCorePageState object directly instead of calling saveDocumentToPageCache on
        the bridge.

        * WebView/WebFrame.mm: (-[WebFrame _bodyBackgroundColor]): Rewrote this to work
        directly with the DOM and renderers rather than using a function on Frame.
