        Web Inspector: URLs are not syntax-higlighted as links in source view.

        This change enables linkifier in the NativeTextViewer. It adds
        "linkify" and "a_node" parse states into the highlighter in order
        to detect links and distinguish between resource and external ones.
        Contains drive-by fix for the webkit-html-* styles and moves them to the
        common location.
