title: node-inspector shows 'No Properties' for objects
body: <p>I'm pretty new in the debugging scene, especially with node-inspecor.</p>
  
  <p>After I had installed node-inspector, I started my simple node app with the --debug parameter and was able to see the debug view at localhost:8080/debug?port=5858.</p>
  
  <p>When I let the app stop at this breakpoint: </p>
  
  <pre><code>router.get('/people', function(req, res) {
      var num = 1;
      var str = 'rarf';
      var obj = {x: 1, y: 2}
  
      console.log(req)    // breakpoint
  });
  </code></pre>
  
  <p>and hover with the curser on the identifier, it shows as follows:</p>
  
  <ul>
  <li>req: <strong>Incoming Message</strong> - No Properties </li>
  <li>res: <strong>Server Response</strong> - No Properties</li>
  <li>str: "rarf"</li>
  <li>num: 1</li>
  <li>obj: <strong>Object</strong> - No Properties</li>
  </ul>
  
  <p>Why can't I see the properties of objects?</p>
