[evolution-data-server] EServerSideSource: Add an "exported" property.

[Matthew Barnes <mbarnes src gnome org>]

commit 1d00bd4960e296a32810ca920d78d26245e9bc09
Author: Matthew Barnes <mbarnes redhat com>
Date:   Thu Jun 21 08:40:54 2012 -0400

    EServerSideSource: Add an "exported" property.
    
    Read-only boolean property indicates whether the source has been
    exported over D-Bus.  Basically just queries the registry server
    for itself.
