joeduffy c478ffbe40 Preserve blank ""s in RefParts 
This changes the logic when parsing RefParts so that we can actually
round-trip them faithfully when required.  To do this, by default we
preserve blank ""s in the RefPart fields that are legally omitted from
the Ref string.  Then, there is a Defaults() method that can populate
the missing fields with the defaults if desired.
