    Use gnc_numeric_multiply instead of Guile's * form for computing prices.
    
    Partly fixes bug 798550 (https://bugs.gnucash.org/show_bug.cgi?id=798550)
    
    Guile's * form when applied to rationals doesn't reduce and since
    guile uses gmp for unlimited precision arithmetic produces numbers
    that can't be passed back to C functions because they're too big for
    any normal C integer types.
