    [report-utilities] more efficient gnc:accounts-get-commodities
    
    don't create intermediate lists which are immediately used and
    discarded.
    
    don't locale-compare commodity names, which has locale-transform
    overhead, and creates lots of temporary strings.
    
    testing for duplicates via O(N) member is very adequate because
    num(unique commodities) is expected to be small.
    
    use the stack when accumulating commodities, avoiding need to prepend
    and reverse.
