        More menulist cleanup/tweaking.

        * html/HTMLSelectElement.cpp:
        (WebCore::HTMLSelectElement::setSelectedIndex): Renamed 'index'
        parameter to 'optionIndex' for clarity.
        (WebCore::HTMLSelectElement::menuListDefaultEventHandler): Skip over
        items that are not enabled <option> elements when using arrow keys, and
        make sure we pass an option index to setSelectedIndex.
        * platform/PopupMenu.h:
        (WebCore::PopupMenu::setWasClicked): Specify default argument.
        * rendering/RenderMenuList.cpp:
        (WebCore::RenderMenuList::setTextFromOption): Strip whitespace from
        option text before setting the control text so that options within
        <optgroup>s don't appear indented in the actual control.
