NOTE: This issue is part of the "SymfonyCon 2014 Madrid Hackday" effort to add logs for every 2.7 deprecated feature. This is needed before removing those features in 3.0 version. Please, add you name in a comment of this issue if you are going to work on this.

The events PRE_BIND, BIND and POST_BIND were renamed to PRE_SUBMIT, SUBMIT and POST_SUBMIT.

Before:

$builder->addEventListener(FormEvents::PRE_BIND, function (FormEvent $event) {
   // ...
});

After:

$builder->addEventListener(FormEvents::PRE_SUBMIT, function (FormEvent $event) {
   // ...
});

The form constants are marked as deprecated, but I don't know if we should also generate logs whenever they are used from any part of the code. If this is not necessary, please close this issue.
