title: How to overwrite FOS user bundle form labels
body: <p>I have a hard time overwriting labels that the FOS user bundle for Symfony2 uses.</p>
  
  <p>I'm already overwriting the Form class, but there is no option for elements like "setOption", only getters.</p>
  
  <p>I could just remove an element and than add it again with the proper label but this seems like an overkill. Is there any nice way of overwriting options on form elements, or just translation keys, perhaps?</p>
