UPGRADING TO 0.8.3 FROM ANY OTHER VERSION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There has been another table format change. This change supports 16
character usernames and should optimise the performance a bit by tuning the
columns to their optimum lengths.

You should run the nuke-all.pl script, and re-populate your MySQL tables
before running this version.

Sorry there isn't a cleaner upgrade path, but this is still very much
in-Development code.
