Generate HTML doc filenames with subject slugs
Generate HTML doc filenames with subject slugs

This tweak generates html filenames using the [[id-string]] tags at
the top of parts and chapters, so that some semantically-interesting
content is embedded in the URL, instead of generating strictly
structural filenames like "ch01.html".
