title: how to turn off loading the layout in ZfcAdmin module for ZF2
body: <p>i'm trying to turn off the layout for some controllers in zfc-admin. Unfortunately all the methods i've found does the exact opposite. turns off the views and loads the layout.</p>
  
  <p>Eg.</p>
  
  <pre><code>$viewModel = new ViewModel();
          $viewModel-&gt;setTerminal(true);
          return $viewModel;
  </code></pre>
  
  <p>Is something in the configuration of ZfcAdmin that disturbs the usual functionality of setTerminal() method ?</p>
