title: SonataAdminBundle custom rendering of text fields in list
body: <p>I'm using symfony2 and SonataAdminBundle.
  I have a simple Entity called Post in which I have content field that is basically html text (from a ckeditor for the record). I need to display in the Post list the content field as raw html, without escaping it.
  Hacking base_list_field template like this</p>
  <pre><code>{% block field %}{{ value|raw }}{% endblock %}
  </code></pre>
  <p>works, but it's clearly not the proper way.</p>
