Title: credit card validation refactoring using credit_card_validations

this solves #52

- removed obsolete brands
- credit_card_validations supported brands
- added ability to validate by multiple brands, eg type: [:amex, :visa]
- fixes luhn validation checks (not all credit card brands use lunh validation)
- more strict validation (valid lunh is not enough to detect brand)
