        Turn on WebCore context menus.

        * dom/EventTargetNode.cpp:
        (WebCore::EventTargetNode::defaultEventHandler): Turn on WebCore 
        menus.
        * page/ContextMenuClient.h: Name change and have the 
        former getCustomMenuFromDefaultItems function return the 
        PlatformMenuDescription since it feels funny to have the client set 
        the new platform description.
        * page/ContextMenuController.cpp:
        (WebCore::ContextMenuController::handleContextMenuEvent): Above 
        name change.
        (WebCore::ContextMenuController::contextMenuItemSelected): Use

        (WebCore::createAndAppendSpeechSubMenu): Fix silly mistake -- make 
        "Stop speaking" actually stop speaking.

        Turn on WebCore context menus. Delete a bunch of WebKit context 
        menu code that is no longer needed.

        * DefaultDelegates/WebDefaultContextMenuDelegate.m: Removed a lot 
        of code from this class. This class only still needs to exist for 
        PDF context menus, so we only need to deal with the menu items that 
        might possibly be added to a PDF context menu.
        (-[WebDefaultUIDelegate 
        menuItemWithTag:target:representedObject:]): Same.
        (-[WebDefaultUIDelegate 
        webView:contextMenuItemsForElement:defaultMenuItems:]): Same.
        * WebCoreSupport/WebContextMenuClient.h: Name change and have the 
        former getCustomMenuFromDefaultItems function return the 
        PlatformMenuDescription since it feels funny to have the client set 
        the new platform description.
        * WebCoreSupport/WebContextMenuClient.mm: Same.
        (WebContextMenuClient::getCustomMenuFromDefaultItems): Same. Also 
        move in some code that used to be in _menuForElement.
        * WebView/WebHTMLView.m: Deleted a bunch of un-used functions
        (-[WebHTMLView menuForEvent:]): Turn on menus, and append the 
        Inspect Element item. 
        * WebView/WebHTMLViewPrivate.h: Deleted a bunch of un-used 
        functions.
        * WebView/WebView.mm:
        (-[WebView _menuForElement:defaultItems:]): Removed a lot of code 
        from _menuForElement that now makes more sense elsewhere. Only PDF 
        context menus use this function now. Hopefully we can just get rid 
        of it soon, too.
