[evolution] Add "forward-style-name" setting.

[Matthew Barnes <mbarnes src gnome org>]

commit c8bbe0df730a8252f062b0aaf98adac9aabd7542
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sun Mar 10 10:10:47 2013 -0400

    Add "forward-style-name" setting.
    
    Replaces the "forward-style" setting, which is now deprecated.
    
    The new setting uses an enum type compatible with EMailForwardStyle.
