I wanted an easy way to list all the Stow chapters in a table, and decided on a new category, mdtPrimarySourceStowChapter, which is added to the chapter files when they're generated. To make that work in the build, I had to rewrite the XML category file generation process so that it works from the site/xml/original documents (where these generated files are) rather than the XML source in /db/data (where they're not). In the process of doing that, I cleaned up the globals module so that it has no hard-coded paths in it; they're all relative to the baseDir now.
