ok... I've thought about it some more, and I came to the conclusion
that all of the CREATE TABLE (if not exists) items in the cvs.sql
should be BEFORE everything else.  Those statements are already
safe from errors that would make an update fail, so they should
be done first to ensure the tables are in a known state, then
all of the changes to table structures can be made after that
in the order from most recent to oldest.

I think that sequence of updates to the database will be the
safest/cleanest/best way to ensure desired database structure.

I'm cleaning up my version of cvs.sql in this fashion and will
re-submit a patch for MC/database/cvs.sql and MC/database/mc.sql.
