title: Mustache template with unknown properties name
body: <p>Is it possible to template an array of object with unknown property?</p>
  
  <pre><code>var objs: [{
    propA: 'A',
    propB: 'B',
    propC: 'A',
    propD: 'B'
  }];
  </code></pre>
  
  <p>And the template could be:</p>
  
  <pre><code>&lt;ul&gt;
    &lt;li&gt;{{property_name}}: {{property_value}}&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
