Formatting

Hi, firstly thank you for this nice credit card form.

My issue is when I chose a saved credit card (on browser) the value that get submitted is formatted "xxxx xxxx xxxx xxxx" so it generate error (I tried to remove the space (reformat) using a jquery with multiple methods without touching card.js but the last value of the card number is always formatted), so when I turn off formatting "formatting: false", the card doesn't detect the card type (visa..)

I hope you get what I mean ^^

Start by reproducing the saved-credit-card browser flow described in the issue with card.js, comparing formatting enabled with formatting: false. Check the submitted card-number value and card-type detection; done means saved-card submissions are accepted without spaces while card type detection still works.
