        - exposed many new commands to the DOM Document executeCommand function by
          merging the JSEditor and Editor executeCommand implementations
        - replaced the execCommand function with a EditorCommand class
        - replaced the WTF::StrHash<> class template with the WebCore::StringHash class
        - replaced the WTF::CaseInsensitiveHash<> class template with the
          WebCore::CaseFoldingHash class

        * WebCore.base.exp: Updated.
        * WebCore.pro: Added EditorCommand.cpp, removed JSEditor.cpp.
        * WebCore.vcproj/WebCore.vcproj: Ditto.
        * WebCore.xcodeproj/project.pbxproj: Ditto.
        * WebCoreSources.bkl: Ditto.

        * dom/Document.cpp:
        (WebCore::Document::Document): Removed code to set up m_jsEditor.
        (WebCore::Document::~Document): Removed code to delete m_jsEditor.
        (WebCore::command): Added. Helper function that gets an Editor::Command.
        (WebCore::Document::executeCommand): Changed to use Editor::Command instead of
        JSEditor.
        (WebCore::Document::queryCommandEnabled): Ditto.
        (WebCore::Document::queryCommandIndeterm):
        (WebCore::Document::queryCommandState): Ditto.
        (WebCore::Document::queryCommandSupported): Ditto.
        (WebCore::Document::queryCommandValue): Ditto.

        * dom/Document.h: Removed JSEditor, jsEditor, m_jsEditor. Changed to
        use CaseFoldingHash.

        * editing/Editor.cpp:
        (WebCore::Editor::selectionForCommand): Renamed from selectionForEvent and
        made into a member function so it is accessible from the new EditorCommand.cpp file.
        Also changed to get the selection from the passed-in frame instead of from the
        page, because this should work on the targeted frame unless the event overrides it.
        (WebCore::Editor::handleKeypress): Updated for selectionForCommand change.
        (WebCore::Editor::handleInputMethodKeypress): Ditto.
        (WebCore::imageElementFromImageDocument): Renamed and changed to return
        a HTMLImageElement instead of a Node*.
        (WebCore::Editor::canCopy): Updated for name change.
        (WebCore::Editor::selectionUnorderedListState): Updated for TriState change.
        (WebCore::Editor::selectionOrderedListState): Ditto.
        (WebCore::Editor::selectionStartHasStyle): Make type of local more specific.
        (WebCore::updateState): Moved here from Frame.
        (WebCore::Editor::selectionHasStyle): Ditto.
        (WebCore::Editor::Editor): Initialize m_shouldStartNewKillRingSequence.
        (WebCore::Editor::insertTextWithoutSendingTextEvent): Updated for
        selectionForCommand change.
        (WebCore::Editor::copy): Updated for imageElementFromImageDocument change.
        (WebCore::Editor::toggleBold): Call the ToggleBold command via the command
        machinery since it's no longer in this file as a local function.
        (WebCore::Editor::toggleUnderline): Call the ToggleUnderline command.
        (WebCore::Editor::setBaseWritingDirection): Change type of argument and of
        local variable.
        (WebCore::Editor::addToKillRing): Moved here from EditorMac. Not useful
        without a kill ring, but it's relatively straightforward to implement one.
        (WebCore::Editor::appendToKillRing): Put default implementation here for
        platforms other than Mac. We should probably put a simple kill ring
        implementation here -- doesn't need to be shared with the OS oh platforms
        other than Mac.
        (WebCore::Editor::prependToKillRing): Ditto.
        (WebCore::Editor::yankFromKillRing): Ditto.
        (WebCore::Editor::startNewKillRingSequence): Ditto.
        (WebCore::Editor::setKillRingToYankedState): Ditto.

        * editing/Editor.h: Moved the TriState enum here instead of inside the
        Frame class. Added EditorCommandSource enum. Moved selectionHasStyle
        here from the Frame class. Added Editor::Command class with five functions
        for the various things you can do with a command (execute it, check if it
        can be used, and its state and value). Changed hte parameter of
        setBaseWritingDirection to be a const String& rather than a String.
        Got rid of the kill-ring-related operations, but added the kill ring
        functions themselves. Made selectedRange() public. Made the
        m_startNewKillRingSequence not Mac-specific and added "should" to its
        name.

        * editing/EditorCommand.cpp: Copied from WebCore/editing/Editor.cpp.
        Retained only the editing commands.
        (WebCore::targetFrame): Moved to the top of the file.
        (WebCore::executeApplyStyle): Added. Helper function for commands
        that need to apply styles.
        (WebCore::executeToggleStyle): Added. Helper function for commands
        that need to toggle styles based on the style of the start of selection.
        (WebCore::executeApplyParagraphStyle): Added. Like executeApplyStyle, but
        for paragraph styles.
        (WebCore::executeInsertFragment): Added. Helper function for commands
        that need to insert a DOM fragment.
        (WebCore::executeInsertNode): Added. Helper function for commands that
        need to insert a tree rooted in a single DOM node.
        (WebCore::stateStyle): Added. Helper function for the state of commands
        that represent style.
        (WebCore::valueStyle): Added. Helper function for the value of commands
        that represent style.
        (WebCore::canScroll): Added. Helper functions for some move and scroll
        commands that need to determine if the renderer they are in can scroll.
        (WebCore::unionDOMRanges): Moved here from EditorMac.

        - change more editing commands to use WebCore::Editor
        - change to use the new WebCore::Editor::command() function

        * WebView/WebHTMLView.mm: Changed alignCenter, alignJustified, alignLeft,

        insertTabIgnoringFieldEditor, outdent, selectAll, selectToMark, setMark,

        (-[WebHTMLView coreCommandBySelector:]): Added. No longer converts case of the
