2004-04-05  Sivaiah Nallagatla <snallagatla@novell.com>

        * e-book-backend-groupwise.c : added code to build groupwise filter from
        the query passed to get_contact_list and start_book_view functions
        modified e_book_backend_groupwise_start_book_view and
        e_book_backend_groupwise_get_contact_list to make use of filter
        Also included gnome-i8n.h
