2000-10-26  Damon Chaplin  <damon@helixcode.com>

	* e-dateedit.[hc]: updated to emit "changed" when appropriate, which
	turned out to be amazingly difficult :(
	Also added e_date_edit_get/set_date() to get/set just the date.
	Added e_date_edit_date_is_valid() & e_date_edit_time_is_valid() so
	you can check if the user has tried to enter an invalid date.
	(All the get_date/time functions return the last valid date entered.)

	* test-dateedit.c: updated a bit.
