        Initial implementation of popup menu control.  This can be turned on by setting -webkit-appearance: menulist on a select element.

        * WebCore.xcodeproj/project.pbxproj: Added RenderMenuList.h, RenderMenuList.cpp, RenderPopupMenu.h, RenderPopupMenu.cpp,
        RenderPopupMenuWin.h, RenderPopupMenuMac.h, RenderPopupMenuMac.mm,

        * dom/Node.cpp:
        (WebCore::Node::renderStyle): Added. Returns the renderer's style.  If there's no renderer, returns's a RenderStyle that's kept by the node.
        This is important for HTMLOptGroupElement and HTMLOptionElement, which don't have renderers.
        (WebCore::Node::setRenderStyle): Added.
        * dom/Node.h:
        * dom/Element.cpp: (WebCore::Element::recalcStyle): Updated to use renderStyle so recalcStyle will work for HTMLOptionElements and HTMLOptGroupElements.

        * css/cssstyleselector.cpp: Updated to call renderStyle method on the node, so resolving style works on elements w/o renderers that cache style.
        (WebCore::CSSStyleSelector::initForStyleResolve):
        (WebCore::CSSStyleSelector::locateCousinList):
        (WebCore::CSSStyleSelector::canShareStyleWithElement):
        (WebCore::CSSStyleSelector::locateSharedStyle):
        (WebCore::CSSStyleSelector::checkOneSelector):

        * css/html4.css: Removed display:none from options and optgroups, since we're now caching style for these elements.
        Added font-weight styles for option and optgroup.

        * html/HTMLOptGroupElement.h: Added m_style to keep track of a RenderStyle for the element, even though we aren't creating a renderer.
        This will allow us to honor style for optgroups and options for popup menus (and eventually list boxes too).
        (WebCore::HTMLOptGroupElement::rendererIsNeeded): Added.
        (WebCore::HTMLOptGroupElement::renderStyle): Added.

        and if we're not creating a list box renderer.
