for osCommerce Online Merchant v2.2

During testing of my "shop-to-be", I got tired of signing on each time. Furthermore the enthousiastic greeting from the standard OSC-software, calling me by name, but not really knowing who I was, became rapidly annoying. And when it annoys me, it probbably also annoys my customers! And annoyed customers is *not* what I want... This contribution provides a way to deal with this. Basically, next to the email-address (which is already stored in a cookie by standard OSC-software), it also stores the password (security: see readme.txt). When the customer returns, this information is used to execute an automatic signin.
