SF2 - FOSUserBundle - Ability to drop username fields

[phillipsnick]

Potential hack found here FriendsOfSymfony/FOSUserBundle#555 (comment)

Some details on using the event listeners here https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/controller_events.md

As username can't be null a quick fix has been added to the user entity

    public function setEmail($email)
    {
        if (is_null($this->getUsername())) {
            $this->setUsername(uniqid());
        }

        return parent::setEmail($email);
    }

Also investigate dropping from sonata table
