[project @ 2005-04-13 21:58:28 by bursa]
Add fallback field to struct box for object fallback content. Add some checks for tree consistency to box_dump(). Rename struct plugin_params to object_param. Clean up box_object(), box_embed(), box_iframe(), and box_image(). Implement object fallback to contents if the fetch or conversion fails. svn path=/import/netsurf/; revision=1627
