Currently when mistakenly we type a [Custom Constraint Validator class](http://symfony.com/doc/current/validation/custom_constraint.html#creating-the-validator-itself) or the "alias name" from [validator service](http://symfony.com/doc/current/validation/custom_constraint.html#constraint-validators-with-dependencies) (which would occurs frequently for newcomers) is shown `ClassNotFoundException`:
> Attempted to load class "alias_name" from namespace "Symfony\Component\Validator".
Did you forget a "use" statement for another namespace?
500 Internal Server Error - ClassNotFoundException
**This PR tries to improve the error message when this happen.**
But I'm not sure about the exception class used ([`InvalidArgumentException`](https://github.com/yceruto/symfony/blob/master/src/Symfony/Component/Validator/Exception/InvalidArgumentException.php)) : ?
* [`ConstraintDefinitionException`](https://github.com/yceruto/symfony/blob/master/src/Symfony/Component/Validator/Exception/ConstraintDefinitionException.php) would be another option, because the source of the error comes from the custom [`Constraint`](https://github.com/yceruto/symfony/blob/master/src/Symfony/Bundle/FrameworkBundle/Validator/ConstraintValidatorFactory.php#L68) definition.
The text message more convenient from this little mistake: ?
* This mistake happen for two reason: FQCN or alias name supplied by constraint not found.
* The constraint validator service was declared incorrectly (missing alias)
* Perhaps some hint how the developer should resolve the mistake.
Maybe some documentation core member would help me ?
