2. Fixed a lot of general comments issues regarding HTML vs. Plain/Text, attachments, etc.
navigation-procs-oracle.xql: we inherited a query from aD that sorted backwards, messing up the database-derived nav bars generated from the site map.
The rest is partial work towards getting glossary to work. After running the query dispatcher it no longer worked even for Oracle due to a bunch of duplicate query names in several files. Boo-hiss...
