BE - Add fee/fine tokens to patron notices

Use cases - Manual fee/fines

• A patron rents a locker for $15.00. A notice will be sent to the patron to indicate the fee they've incurred. No items are associated with this fee.
• A patron rents a locker for $15.00 and now $15.00 is paid (in full). A notice will be sent to the patron to indicate that a $15.00 payment was received.
• A patron rents a locker for $15.00 and now $10.00 is waived and $5.00 is paid. A notice will be sent to indicate that $10.00 was waived and $5.00 was paid.
• A patron rents a locker for $15.00, $5.00 was paid on Aug 5, 2019 and now $10.00 is paid. A notice will be sent to indicate that $5.00 was paid on Aug 5, 2019 and $10.00 was paid now.

• A patron returns an item that is damaged. A $20.00 fee is incurred. A notice will be sent to the patron to indicate the fee they've incurred with a reference to the damaged item.

Use cases - Automated fee/fines (currently in development, including for reference only)

• A patron borrows an item, it's overdue by 5 days so an automated fee of $1.00 is incurred which triggers a notice sent to the patron with the details of the fee.
• A patron borrows an item, it's overdue by 10 days so an additional automated fee of $1.00 (on top of the already $1.00 incurred above) is incurred which triggers a notice sent to the patron with the details of the fee.

Fee/fine tokens:
