card_type not available through Customer.retrieve

[rockymeza]

I thought it would be nice to do something like this:

>>> customer = dinero.Customer.retrieve('xxx')
>>> card = customer.cards[0]
>>> print 'Card on File:'
>>> print '{} ({})'.format(card.card_type, card.last_4)

But it doesn't work. This seems to be a limitation on the Authorize.net side though.

I thought I would just report this in case anybody else was having this problem.
