title: Remove or customize the embeded form label
body: <p>When I set up my formtype file like this:</p>
  
  <pre><code>$builder-&gt;add( 'producer', new ProducerType() );
  </code></pre>
  
  <p>it always return me a general title(label) for the embeded form, like "producer", how can I remove or customize this label?</p>
  
  <p>UPDATE: the latest Fosuserbundle has been removed this annoyed lable</p>
