Nowhere near done yet, but checking in a snapshot of semi-working code. There is some simultaneous support for both with and without use of the Invoice/Receipt account. I want to do away with them completely, but will need to change how sitelink payments are mapped (right now, they split a payment into multiple parts to match the charge).
