    Bug 797770 - Reconciliation report does not consider credit transactions
    
    A few preparatory changes...
    
    * calculated-cells augmented to allow 7 fields instead of 6. 7th field
    defines whether cell is mergeable for subtotal-table. note only the
    first element in calculated-cells is currently considered for the
    subtotal-table accumulator.
    
    * backward compatible upgrade to trep-engine's add-subtotal-row --
    handles both 6-field and 7-field calculated-cells. 7th field, if
    missing, is assumed to be #f.
    
    * transaction report: unlock subtotal-table when amount='double in
    addition to 'single.
    
    And finally the bug fix itself:
    
    * reconcile-report: fix subtotal-table accumulator to consider both Dr
    and Cr
