[evolution/account-mgmt: 39/51] Add 'mail-config' module.

[Matthew Barnes <mbarnes src gnome org>]

commit d9ef11ac5fdc3c0e6e528ca88ae0fdcfb254e429
Author: Matthew Barnes <mbarnes redhat com>
Date:   Fri Feb 17 10:47:06 2012 -0500

    Add 'mail-config' module.
    
    This breaks a good chunk of logic out of EMAccountEditor and hopefully
    makes it less brittle.  Because honestly, every time I fix one thing in
    EMAccountEditor it breaks three other things.  It's unmaintainable.
