        Add orientation menu items

        * shell/ev-page-cache.c: (ev_page_cache_clear):
        * shell/ev-page-cache.h:

        Add api to clear the cache

        * shell/ev-view.c: (setup_caches), (clear_caches),
        (ev_view_set_document), (ev_view_zoom_out),
        (ev_view_set_orientation):
