add new validations

[Jorge Brunal]

Hello, excellent application. 👍 💯
I just found a very good example on morioh
Is it possible to add other validations such as those of the site, with regex?

• American Express: - Starting with 34 or 37, length 15 digits.
• Visa: - Starting with 4, length 13 or 16 digits.
• MasterCard: - Starting with 51 to 55, length 16 digits.
• Discover: - Starting with 6011, length 16 digits or starting with 5, length 15 digits.
• Diners Club: - Starting with 300 to 305, 36 or 38, length 14 digits.
• JCB: - Starting with 2131 or 1800, length 15 digits or starting with 35, length 16 digits.

Sorry for the translation, I'm using Google translate 😢
