* New: Various code improvements such as a class based plugin structure and improved performace.
* Fix: The link to the Braintree transactions details is now fixed within the donation details screen within wp-admin.
* Fix: Added compatibility for use of multiple Braintree gateways (for instance if you're using WooCommerce's Braintree add-on separately).
* Fix: When a custom donation was given the gateway would incorrectly assign it as a donation level within the receipt despite the correct custom amount being processed.
