    gnus-icalendar.el: Support vcal format timezones
    
    Old version only supported emacs known timezone.
    Here we reuse icalendar code to extract timezone definition from
    vcalendar format.
    
    * gnus-icalendar.el: Support vcal format timezones
    (gnus-icalendar-event--decode-datefield): use icalendar functions to
    compute dates with associated timezone
    (gnus-icalendar-event-from-ical): compute all timezones
