[evolution/account-mgmt: 23/33] Add a source-loader module.



commit 1363dae9ef25130c8bc9dd041cf5342c98cab184
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sun Dec 19 22:38:36 2010 -0500

    Add a source-loader module.
    
    It loads ESources at startup, submits alerts for loading errors,
    and enforces Evolution-specific ESource policies.
