WFC annual meeting check-in app. Saving to github so I don't lose track of it
Bad scan fix, no description
Change: main receipt printing function now returns a string
and this string is sent to the printer AFTER the transaction is
finished in the database. This addresses an issue where timeouts
or other failures of the printer hardware could cause transactions
to run together.

The receipt building stuff is not strictly related, but ReceiptLib.php
does contain references to it so the new modules are committed for
completion. They're only triggered if "newReceipt" in ini.php is set
to 2. I do not recommend doing this in production.
