    Bug 797521 Receivable Aging (beta): prepayments logic doesn't work, appears to use incorrect absolute value logic
    
    Final changes after feedback.
    
    * LHS rows now have rowspan as many as linked rows.
    * use gncInvoiceGetID instead of xaccSplitGetMemo
    * use gncInvoiceGetType instead of gnc-get-action-num to find txn type
    which is unreliable
    * swap type/description to reference/type columns
    * reuse strings
    * URLs generally:
    
      document -> document-editor
    
      monetary -> register; all anchors point to non-APAR account. this
      reinforces the view that APAR account is an implementation detail,
      and most invoice posting/payment activity belong in the Transfer
      account.

    [gnc-lot.h] amend description for gnc_lot_get_earliest_split
    
    this function doesn't necessarily point to the lot opening split.
