Title: Added support for the :notes parameter to Linkpoint

We use the :comments parameter inside the :notes parameter to put information related to the payment (eg., user name, company name, etc.). Those info then show up in the :comment field of a transaction's details report on Linkpoint. Very useful for our accounting people.
