Split the currency picker's browsable list into Priced/Unpriced

The "Currencies" section (not-yet-added currencies) is now two:
"Priced Currencies" and "Unpriced Currencies", partitioned by
whether the active source quotes a rate for each one. "Current
Currency" and "Selected Currencies" are unaffected.
