take an extra param on whether to mark touched (map_sax_start_element):

2001-10-26  JP Rosevear  <jpr@ximian.com>

	* e-pilot-map.c (real_e_pilot_map_insert): take an extra param on
	whether to mark touched
	(map_sax_start_element): use above
	(e_pilot_map_insert): ditto
	(e_pilot_map_write): pass in extra info to foreach call
	(map_write_foreach): if we are in touched only mode, write out the
	map only if its been touched

	* e-pilot-map.h: add new member
