Extract the element implementation logic to function mods in <webview>.

  function mods end with "$".

"element" inside <webview> is currently the plugin <object> element, i.e.
  the browser plugin. This CL makes it possible to provide a different
  implementation for the element. This CL also provides a stub
  using <iframe>. This will be used by the <webview> using OOPIF
