- more preparation for splitting up Frame into sub-pieces
        - removed unnecessary includes from Frame.h

        * page/Frame.h: Removed unneeded includes and forward declarations.
        Added additional forward declarations. Removed the constant
        NoXPosForVerticalArrowNavigation, now moved inside SelectionController.
        Created sections of functions to be moved into Chrome, Editor,
        EventHandler, FrameLoader, SelectionController, and the Platform
        directory, as well as marking one function for deletion.

        * page/FramePrivate.h: Removed the definition of the constructor and
        destructor and removed unnecessary includes.

        * page/FrameView.h: Removed unneeded forward declarations and friend
        declarations. Created a section of functions and data to be moved into
        EventHandler.

        * bridge/mac/FrameMac.h: Removed unneeded forward declarations.
        Created sections of functions and data to be moved into Chrome,
        Editor, EventHandler, FrameLoader, and the Platform directory.

        * bridge/mac/WebCoreFrameBridge.h: Removed obsolete comment.
        Removed unused methods areScrollbarsVisible,
        nextValidKeyViewOutsideWebFrameViews, and fileWrapperForURL:.

        * page/Frame.cpp:
        (WebCore::Frame::begin): Added an overload, so Frame.h doesn't have
        to include KURL.h just for the KURL default constructor.
        (WebCore::FramePrivate::FramePrivate): Moved here from FramePrivate.h.
        (WebCore::FramePrivate::~FramePrivate): Ditto.

        * page/FrameView.cpp: Removed unused scrollbarMoved and scrollingSelf
        booleans, scrollbarMoved and cleared funcitons.
        (WebCore::FrameView::clear): Moved the code from the cleared
        function in here.
        (WebCore::FrameView::scrollTo): Removed code to set scrollingSelf.

        * bridge/mac/FrameMac.mm: (WebCore::FrameMac::FrameMac): Updated
        for changes to header.

        * editing/SelectionController.cpp:
        (WebCore::SelectionController::setSelection):
        (WebCore::SelectionController::xPosForVerticalArrowNavigation):
        Moved NoXPosForVerticalArrowNavigation into this file.

        * bindings/js/kjs_events.cpp:
        * bindings/js/kjs_html.cpp:
        * bindings/js/kjs_window.cpp:
        * bridge/mac/WebCoreAXObject.mm:
        * bridge/mac/WebCoreFrameBridge.mm:
        * css/cssstyleselector.cpp:
        * dom/Document.cpp:
        * dom/Element.cpp:
        * dom/EventTargetNode.cpp:
        * dom/MouseRelatedEvent.cpp:
        * dom/XMLTokenizer.cpp:
        * html/HTMLBaseElement.cpp:
        * html/HTMLDocument.cpp:
        * html/HTMLEmbedElement.cpp:
        * html/HTMLFrameElementBase.cpp:
        * html/HTMLGenericFormElement.cpp:
        * html/HTMLObjectElement.cpp:
        * html/HTMLTokenizer.cpp:
        * loader/mac/FrameLoaderMac.mm:
        * page/PageState.cpp:
        * rendering/RenderApplet.cpp:
        * rendering/RenderBlock.cpp:
        * rendering/RenderLayer.cpp:
        * rendering/RenderObject.cpp:
        * rendering/RenderPartObject.cpp:
        * rendering/RenderTreeAsText.cpp:
        * xml/XSLTProcessor.cpp:
        Added includes as needed to keep compiling, since there are fewer
        includes in Frame.h.
