x-wr-timezone is a nonstandard prop used to specify a default timezone for a calendar. Previously when importing from ics files we'd ignore this and end up with UTC timezones set for most events if a calendar uses this prop. Now we'll properly default the timezones for events to whatever the x-wr-timezone is for the imported calendar.
