        More WebCore context menu work (still not turned on, however).

        Split ContextMenuItem into its own files and make it a class.

        * WebCore.exp: Updated symbols.
        * WebCore.xcodeproj/project.pbxproj: Added new ContextMenuItem files.
        * platform/ContextMenu.cpp:
        (WebCore::ContextMenu::populate): Code cleanup.
        * platform/ContextMenu.h: Split ContextMenuItem into a separate file,
        removed redundant "Menu" part of platformMenuDescription(),
        setPlatformMenuDescription().
        (WebCore::ContextMenu::ContextMenu):
        (WebCore::ContextMenu::hitTestResult):
        (WebCore::ContextMenu::platformDescription):
        * platform/ContextMenuItem.h: Added. Made ContextMenuItem a
        full-fledged class.
        (WebCore::):
        (WebCore::ContextMenuItem::ContextMenuItem):
        (WebCore::ContextMenuItem::menu):
        (WebCore::ContextMenuItem::platformDescription):
        (WebCore::ContextMenuItem::type):
        (WebCore::ContextMenuItem::action):
        (WebCore::ContextMenuItem::title):
        * platform/mac/ContextMenuItemMac.mm: Added.
        (WebCore::ContextMenuItem::ContextMenuItem):
        * platform/mac/ContextMenuMac.mm: Updated for ContextMenuItem changes.
        (-[MenuTarget forwardContextMenuAction:]):
        (getNSMenuItem): Handle separator items.
        (ContextMenu::appendItem):
        (ContextMenu::itemCount):
        (ContextMenu::insertItem):
        (ContextMenu::setPlatformDescription):
        * page/ContextMenuController.h: Updated declaration, added getter.
        (WebCore::ContextMenuController::contextMenu):

        Added some more context menu plumbing.

        * dom/EventTargetNode.cpp:
        (WebCore::EventTargetNode::defaultEventHandler): Added code to call the
        ContextMenuController when a context menu event is received.
        * page/ContextMenuClient.h: New client method declaration.
        * page/ContextMenuController.cpp:
        (WebCore::ContextMenuController::handleContextMenuEvent): Set the event
        defaultHandled after handling it.
        (WebCore::ContextMenuController::contextMenuItemSelected): Take a
        ContextMenuItem instead of a separate action and title.

        Changed event-handling methods to return bools to signify whether the
        event was handled or not. This is needed so we can know whether to hand
        the event off to the OS. Also restructured some code to use early
        returns instead of nesting ifs.

        * page/EventHandler.cpp:
        (WebCore::EventHandler::handleMousePressEventDoubleClick):
        (WebCore::EventHandler::handleMousePressEventTripleClick):
        (WebCore::EventHandler::handleMousePressEventSingleClick):
        (WebCore::EventHandler::handleMousePressEvent):
        (WebCore::EventHandler::handleMouseMoveEvent):
        (WebCore::EventHandler::handleMouseReleaseEvent):
        (WebCore::EventHandler::handleMouseDoubleClickEvent):
        (WebCore::EventHandler::handleWheelEvent):
        (WebCore::EventHandler::canMouseDownStartSelect):
        * page/EventHandler.h:
        * page/FrameView.cpp:
        (WebCore::FrameView::handleMouseMoveEvent):
        (WebCore::FrameView::handleMouseReleaseEvent):
        * page/FrameView.h:
        * platform/ScrollBar.h: More bool return values.
        (WebCore::Scrollbar::handleMouseMoveEvent):
        (WebCore::Scrollbar::handleMouseOutEvent):
        * platform/Widget.h: Ditto.
        (WebCore::Widget::handleMouseMoveEvent):
        (WebCore::Widget::handleMouseReleaseEvent):

        Reverted the changes made in r17805 so that we can have fewer header
        #includes.

        * page/Page.cpp:
        (WebCore::Page::Page):
        * page/Page.h: Ditto.
        (WebCore::Page::dragCaretController):
        (WebCore::Page::chrome):
        (WebCore::Page::contextMenuController):
