We need to do three kinds of things when processing the canonical metadata database into TEI XML: 1. update metadata in existing files, 2. create new files for poems never before processed, and 3. detect problems such as multiple existing files for the same id. I'm a good way into this, and the basic structure is set up and appears to be working. Ultimately, I think we'll have to manage the whole operation with ant, to construct all the output stuff in a new location, then copy it back over the original tree, because we won't be able to both read and write the same file in one XSLT transformation.

Also reconstructed the two required triggers in the live database to get the related-poems dropdown working again.
