#10 org.hibernate.validator.constraints.CreditCardNumber support

[Craig]

It would be great the dialect could support @CreditCardNumber.

I imagine that simply using pattern="\d+" would be enough. The pattern can't be much more specific than that because credit card number length varies pretty widely from 12-19 digits, and it doesn't seem like a great idea to implement a tighter constraint because of that variation. See https://en.wikipedia.org/wiki/Bank_card_number for details.

[Jose Miguel Samper]

@CreditCardNumber is an Hibernate Validator annotation http://docs.jboss.org/hibernate/validator/5.2/api/org/hibernate/validator/constraints/CreditCardNumber.html

It just implements a modulo algorithm http://en.wikipedia.org/wiki/Luhn_algorithm not a full credit card validation.

In order to be coherent with that we should implement a javascript validation performing the same check.
