Subject: [PATCH] - Added a config option that allows the admin system to run
 off of data from the database. There is a config options in config.txt that
 dictates whether to use the new SQL based system or the legacy admins.txt
 system. If a server is set to use the new system, but a connection cannot be
 established to the database, it reverts to the legacy system, same applies if
 a query to the database returns empty. The config option defaults to use the
 legacy system.
