After finding out that the ereg functions used in the credit card validation have been deprecated as of PHP version 5.30 I updated this contribution to use the corresponding preg funcions instead. I've added a couple of checks to the CVV validation and a way to easily choose which credit cards your store accepts.

If you have already installed this contribution simply replace the cc.php and cc_validation.php files with these new ones then follow steps 14 and 15 of the install instructions. The first language line defined in step 14 is the same as previous versions, the remaining lines are new.
