#include <string.h> for memset

2002-08-06  Jeffrey Stedfast  <fejj@ximian.com>

	* e-cell-progress.c: #include <string.h> for memset

	* e-table.c (e_table_save_specification): Updated to use
	e_xml_save_file() instead of xmlSaveFile(). Also fixed to save to
	a tmp file first.

	* e-table-specification.c (e_table_specification_save_to_file):
	Same as above.

	* e-table-state.c (e_table_state_save_to_file): Same here.

	* e-tree-table-adapter.c
	(e_tree_table_adapter_save_expanded_state): And here too.
