its code is obviously not in working order. Remove.
(minmult, maxmult, configkeys): Unused configuration parameters,
remove.
(tradedesc): Remove code related to mult that had no effect.
(multread, commread, commwrite, commamt, commset, multset, commprice):
Dangerous, because code bypasses ef_read() & friends, remove.
(diss): Commodity cleanup uses the above, remove. Command is disabled
and unlikely to work anyway.
