Log:
Collapse the two transaction currency scrubbing functions into one and fix some bugs.
The most serious bug was that it would, in some cases, set the transaction's currency
to a non-currency commodity.  It also sometimes set the currency directly without calling
xaccTransSetCurrency which skipped a number of side effects.
