commit 4a3a8be18674b7622f3f0b732c3e822f49965eab

    Add piechart report grouping by commodity.
    
    Add a new piechart report that groups by commodity and not by the
    account hierarchy.  This also refactors the existing piechart report
    file a bit, to reuse code where possible and only abstract-out the
    pieces that need to be generalised.
