[Patch 3/9] Ensure configuration values are stored in lower case

[Steve Dickson <SteveD@redhat.com>]

commit 3b192f9d86e13ee0413c4dcc88229e6bc35cb5c9
Author: Steve Dickson <steved@redhat.com>
Date:   Mon Mar 9 13:57:10 2009 -0400

    Store values in lower case. This makes it easier to do string
    comparisons when reading lists from the configuration file.
