- I tidied up most SQL tables to be more consistent with the rest of the
  tables: I changed all "id"s to "xid"s where "x" is the first letter of
  the table name.  I also renamed all remaining "userid"s to "uid"s as I
  mentioned I would do.  Take a look at ./drupal/updates/3.00-to-x.xx.sql
  for the MySQL updates.
