title: Qt: list of dynamic properties set on a given QObject?
body: <p>Using <code>QMetaObject</code> I am able to browse all properties defined at compile-time using <code>Q_PROPERTY</code> macro...</p>
  
  <p>Now I would be able to browse all dynamic properties added at run-time using <code>setProperty()</code>...</p>
  
  <p>Is it possible?</p>
