[evolution] Add ESettingsClientCache.

[Matthew Barnes <mbarnes src gnome org>]

commit a26c98ad5ae39d2b60eb727eea81a9eab1dda01a
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sat Feb 16 10:20:18 2013 -0500

    Add ESettingsClientCache.
    
    Listens for "client-created" signals from its EClientCache.  If the
    newly-created client is an ECalClient, automatically configure its
    default timezone from EShellSettings.
