Changed to use page labels now. Rewrote completely because I didn't

Fri Apr  1 01:59:39 2005  Jonathan Blandford  <jrb@redhat.com>

        * shell/ev-page-action.c: Changed to use page labels now.  Rewrote
        completely because I didn't understand GtkActions.  I should
        read Marco's code more carefully in the future.

        * backend/ev-page-cache.h (ev_page_cache_set_page_label): New
        function
