allow for null CN (parse_person): allow for null sent_by

	* pcs/icalendar.c (parse_person): allow for null CN
	(parse_person): allow for null sent_by

	* pcs/Makefile.am: build icalendar-test

	* pcs/icalendar-test.c: a test which loads an ical file and
	converts it to our internal format, and then saves it back out.
