currency: Make currency pieces be fastsplit

The actual machinery does all the hard work.

This shouldn't have any overall visible functional change.  It just
engages new contraptions during piece creation and load/save, but
right now they shouldn't have any work to do because we don't actually
ever split (or merge) currency.
