1998-04-15  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* eventedit.c (ee_init_general_page): The general_owner may be
	null.  Do the proper thing when creating the label.
	(ee_ok): Update the gnome calendar appropriately.

	* timeutil.h:
	* gncal-year-view.h: Add some missing prototypes.

	* gncal-full-day.c (child_popup_menu): Set the sensitivity of menu
	items according to whether the ical object is being edited or not.

	* eventedit.c (event_editor_new): Set the "being edited" flag on
	the ical object (stored as the ical object's user data).
	(event_editor_destroy): Release the flag.

	* calobj.h: The iCalObject structure now has a generic user_data pointer.
	* calobj.c (ical_object_set_user_data ical_object_get_user_data):
	Functions to set this data.
