[Murray Cumming <murrayc src gnome org>]

commit d57ff116306514fe506089f9e6ed1bbc5bc9966f
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Nov 16 09:23:45 2011 +0100

    Make the Calendar portal work again.
    
    	* glom/mode_data/box_data_calendar_related.[h|cc]: Override
    	create_layout() as a place to call our get_fields_to_show(), like
    	Box_Data_List_Related does. Then fill_from_database() can succeed.
