Still need to do the other objects.

2005-11-05  Jody Goldberg <jody@gnome.org>

	* src/xml-io.c : Delete the original DOM based export.  The pseudo-sax
	  based variant is faster and lighter and there's not much point in
	  maintaining two code bases.

	* src/gnm-so-filled.c (gnm_so_filled_write_xml_dom) : delete.
	* src/gnm-so-line.c (gnm_so_line_write_xml_dom) : delete.
	* src/gnm-so-polygon.c (gnm_so_polygon_write_xml_dom) : delete.
	* src/sheet-object-cell-comment.c (cell_comment_write_xml_dom) : delete.
	* src/sheet-object-image.c (sheet_object_image_write_xml_dom) : delete.
	* src/sheet-object-widget.c
	(sheet_widget_frame_write_xml_dom) : delete.
	(sheet_widget_button_write_xml_dom) : delete.
	(sheet_widget_adjustment_write_xml_dom) : delete.
	(sheet_widget_checkbox_write_xml_dom) : delete.
	(sheet_widget_list_base_write_xml_dom) : delete.
	* src/sheet-object-graph.c (sheet_object_graph_write_xml_dom) : delete.
	(sheet_object_graph_prep_xml_sax) : new.
	(sog_xml_finish) : new.
	(sheet_object_graph_write_object) : use the sax interface.

	* src/xml-sax-read.c (xml_sax_wb) : ICK.  We are actually depenent on
	  the prefix for the namespace.  The change from gmr -> gnm broke the
	  version test here.  Add gnm to fix it.
	(xml_sax_wb_sheetname) : be more flexible and only create a sheet if
	  we really need it.
	(xml_sax_object_start) : implement.
