1052914cb4 Credit cards 
Summary:
Add the ability to parse credit cards and identify the issuer in Duckling.

Credit card numbers are a sequence of 8 to 19 digits, with a few specific digits at the start that identify the card issuer. They also satisfy Luhn checksum (https://en.wikipedia.org/wiki/Luhn_algorithm).
