* If there are over 50 attendees in an event, we only store the
organizer as an attendee (the rest are redacted) and we set
the hasAttendeeData flag to 0
* If the user is the organizer, we reset the owner of the event
to a bogus address, which causes the UI to prevent edits to
the event (we can't upload without losing all of the attendee
information on the server). We also prevent the event from ever
being uploaded (belt & suspenders)
* If the user is an attendee, we allow changes to be uploaded
(this would be attendee status and free/busy), but the list of
attendees on the server is removed.
* We also mark events with redacted attendees, even though we don't
use that information currently. In a future version, however,
we could use this to indicate the redacted state to the user.
