title: FOSUser Bundle manual trigger confirmation email
body: <p>I use the FOSUser Bundle as a basis class for my own User class. Through a webservice it's possible to create new users.</p>
  
  <p>As far as I know it's only triggered when a user registers himself through the registration form.</p>
  
  <p>Is there a way to manual trigger the confirmation email from a controller?</p>
