Problem/Motivation
For the mysql, pgsql and sqlite database drivers do not have to set the module name setting. Those database drivers have their module name setting default to their driver name. Lets do that for all database drivers.
Proposed resolution
Let the database driver module setting when not set, default to the driver name.
