#3 Migrate from AthenaDBMS to MySQL

[Steve Willoughby]

Change out the database access code from the Athena
DBMS to use MySQL instead. Then we need to move
the configuration and site/user info into the database,
allowing admins to use other tools to manage REQADM
as a part of their IT infrastructure without needing
layers of adapting scripts and so forth.

In the process, we will FINALLY* jettison the old ASCII
files where tickets are stored and put everything in the
SQL database.

*and there was much rejoicing.
