Comment 3 for bug 2056204

I've signed off Galen's commit, and added a followup of my own to have the tag table service (used in the angular marc editor) update the in-memory fixed field position map based on the server's configuration. Branch available at:

I won't be hurt if we just take Galen's commit, though. :)
