[evolution] Add "headers-collapsed" setting.

[Matthew Barnes <mbarnes src gnome org>]

commit 09b7686c4a2a359aa8f747719932ccbf12c3103b
Author: Matthew Barnes <mbarnes redhat com>
Date:   Thu Mar 14 21:10:39 2013 -0400

    Add "headers-collapsed" setting.
    
    Replaces "paned-view-headers-state", which was defined as an integer for
    some stupid reason.  Not bothering to migrate the old setting since it's
    one button click.
