Title: Added support for passing optional fields in Litle token based transactions

* Added a LitleCardToken class to make working with tokens similar to credit cards.
* Added missing certification tests for explicit token registration and updated tests for latest test data.
* Updated existing tests to use the new LitleCardToken class in calls to authorize and purchase.
