	(e_addressbook_prompt_save_dialog): new function, a "Do you want
	to save changes?" dialog.

	* gui/widgets/e-addressbook-util.h: add prototype for
	e_addressbook_prompt_save_dialog.

	* gui/contact-editor/e-contact-editor.c (prompt_to_save_changes):

	select save.  return TRUE if the dialog should be closed, FALSE
	otherwise.
	(file_close_cb): check prompt_to_save_changes before closing the
	dialog.
	(app_delete_event_cb): same.

	* gui/contact-list-editor/e-contact-list-editor.c
	(prompt_to_save_changes): call e_addressbook_prompt_save_dialog
	and save the card if they select save.  return TRUE if the dialog
	should be closed, FALSE otherwise.
	(file_close_cb): check prompt_to_save_changes before closing the
	dialog.
	(app_delete_event_cb): same.
