BasicCardResponse: cardholderName should be optional.

[Torlus]

I see at least two cases where this field cannot be returned:

• In France, it is forbidden to provide such information, due to the CNIL rules about personal data and rights.
• Visa, MasterCard, and others provide Anonymous Prepaid Cards, making this information irrelevant.

In my PR #114, I have indeed showed this as optional.

Addressed in PR #114

Adrian, that PR has not been accepted yet and I've in fact closed it awaiting resolution of PR 133 which changes the shape of how PR 114 will be done.

Sorry, my mistake. I saw that @adrianba had merged #131 which included the same change but now see he picked only the one specific commit.
