Credit Card Number Database Mask

for osCommerce Online Merchant v2.2

I took two other contributions and combined the ideas from both. This contribution allows you to mask the credit card number from within the order screen. It will then save the masked cc number in the database. This is for those store owners that want to minimize security risks. Keep in mind that this contribution does over write the cc number for that order. You may want to keep a hard copy of the order for your records.
