Subject: the beginning of the great id format migration.  This makes asset
 uuids no longer binary.  I've tested this migration a few times, and it seems
 working in all the scenarios I've found but it wouldn't hurt to backup your
 asset db before running this as it does touch a very sensitive part of our
 content system.
