[evolution] Adapt to Camel API changes.

[Matthew Barnes <mbarnes src gnome org>]

commit 8ad0c51edff9677ca22c46257f4a596dc23d2055
Author: Matthew Barnes <mbarnes redhat com>
Date:   Wed May 5 21:47:44 2010 -0400

    Adapt to Camel API changes.
    
    This also removes the boxed CamelObject GType, since CamelObject is an
    honest-to-goodness GObject now.
