    [category-barchart] simplify report definitions
    
    instead of list-accessors, use (ice-9 match) to assign names to list
    items. remove ugly 'tip-and-rev' hack.
    
    also remove hidden option 'reverse-balance?' and pass it as an
    argument to the renderer.

    [income-gst-statement] no need to reverse report amounts
    
    this report handles reversal of income amounts and shouldn't
    re-reverse according to originating split's account type.
    
    also friendly-fn should be #f instead of (lambda (a) "") because the
    former is handled specifically in trep-engine's add-subheading to
    display a blank cell.
