added e_date_edit_get/set_make_time_insensitive() which makes the time

2001-08-16  Damon Chaplin  <damon@ximian.com>

	* e-dateedit.c: added e_date_edit_get/set_make_time_insensitive()
	which makes the time field insensitive rather than hiding it.
	I'm not sure we're going to actually use this now, though.
