Replace iCalendar parser.
The old iCalendar parser was a direct port of my C parser, which
unfortunately clashed with guile's evaluation model, and was therefore
really slow.
This new one is much schemier [sic?], and therefore much faster. On my
laptop the parse time went from around 10s to 2.5s, so a 4x speedup!
