Bug 12054: Ability to serialize an element subtree (into clipboard?) from the DOM inspector
        http://bugs.webkit.org/show_bug.cgi?id=12054

        - Add support code for routing copy events to the focused element.
        - Implement copying the currently selected DOM node. The node
          and it's subtree is copied to the clipboard. If the node has no
          outerHTML, the nodeValue is copied (text nodes, etc.)
        - Implement copy for the resource sidebar. The URL is copied for the
          currently selected resource.
