[Tsaukpaetra]

Ad an option to allow automated refunds for authorized users to easily refund badges using the PayPal data received from the transaction.
This action will invoke an endpoint call, which will cause PayPal to send a notice to the recipient upon completion, and upon success ConCrescent will automatically mark the badge refunded, appending the results to the PayPal field.
