title: TinyMCE4 url list
body: <p>I upgraded TinyMCE3 to TinyMCE4 in my CMS, but unfortunatelly <a href="http://www.tinymce.com/wiki.php/Configuration3x%3aexternal_link_list_url" rel="noreferrer">external_link_list_url</a> and <a href="http://www.tinymce.com/wiki.php/Configuration3x%3aexternal_image_list_url" rel="noreferrer">external_image_list_url</a> are not working.</p>
  
  <p>Is there any plugin to get external_link_list_url and external_image_list_url from TinyMCE3 working again?</p>
