    [new-owner-report] LHS invoice->payment LINK/PAYMENT merge
    
    * invoice->payment LINK or PAYMENT txns are handled identically. Merge.
    * reorder definitions in document handler.
    * rename variable 'invoice' to 'document'; invoice was clashing with
      outer variable. This fixes a credit-note negation bug.
