title: Sonata Admin remove the batch column from list view
body: <p>Symfony 2.3.25, SonataAdminBundle</p>
  
  <p>If i remove the 'delete' route from my admin by</p>
  
  <pre><code>$collection-&gt;clearExcept(array('list'));
  </code></pre>
  
  <p>in configureRoutes I get no 'batch' column in List View, which is what I want.</p>
  
  <p>But I need the 'delete' action. </p>
  
  <p>When I configureRoutes:</p>
  
  <pre><code>$collection-&gt;clearExcept(array('list', 'delete'));
  </code></pre>
  
  <p>I get the 'batch' column back, which I do not want. I do not want any batch actions or batch columns or anything batch. </p>
  
  <p>I do want a 'Delete' button per row in an Actions column, which I get.</p>
  
  <p>How do I suppress the batch column in list view?</p>
