[evolution-data-server] gnome-online-accounts: Add an EDataFactory extension.

commit 4b0ccdb2148f3a9b0dfd362fc91cef9fcd6b4d51
Author: Matthew Barnes <mbarnes redhat com>
Date:   Mon Nov 12 11:38:45 2012 -0500

    gnome-online-accounts: Add an EDataFactory extension.
    
    This extension takes over for the GOA bits in EDataBookFactory.
    
    Install this extension to both the addressbook and calendar backend
    directories, even though only EBookBackendGoogle uses it at present.
