Rework properties code to take only EvPropertyInfo in the constructor so

2005-06-04  Marco Pesenti Gritti <mpg@redhat.com>

        * backend/ev-document-info.h:
        * backend/ev-document.c: (ev_document_info_free):
        * data/evince-properties.glade:
        * pdf/ev-poppler.cc:
        * ps/ps-document.c: (ps_document_get_info):
        * shell/ev-properties.c: (ev_properties_format_date),
        (set_property), (ev_properties_new):
        * shell/ev-properties.h:
        * shell/ev-window.c: (ev_window_cmd_file_properties):

        Rework properties code to take only EvPropertyInfo
        in the constructor so that it can be useful for
        nautilus plugin too.

        Deal with backends that doesnt support some properties.
        Make set property code generic.
