Bug 23228: Add option to automatically display payment receipt for printing after making a payment

Some libraries would like an auto-popup after making a payment so librarians don't have
to navigate to the accounts page, locate the new payment, then click the print button.

Test Plan:
1) Apply this patch
2) Run updatedatabase.pl
3) Make a payment, note no difference in behavior
4) Enable the new syspref FinePaymentAutoPopup
5) Make a payment, note the popup for the payment receipt
