Yes and no - ordering fixed most, and not adding undefined weights or
facet_order, but there are some remaining differences:
1 - Facet order not set in default file
2 - LC-card-number - comes out in lower case because we have it twice, once for
authorities and once for biblios - these get combined when adding to DB because
they all go in to 'search_field' which doesn't separate bibs/auths - I don't
think the matters. There does seem to be convention of Auth fields being
capitalized and bibs fields not, but I don't believe we rely on this or need to
3 - Default mapping file is not strictly alphabetized - date-of-publication
moves on export

Probably a good compromise is to generate the mapping file from this bug once
it passes QA and use the exported file as the default from now on. Consider it
a cleanup of the file
