* The meaning of a busy status of "Busy" is uncertain; it could mean
"Accepted" or "Tentative", depending on whether the event was
created via OWA/Outlook or EAS
* We have interpreted it as "Accepted", which prevents the user from
actually accepting the event (as a state change is required for us
to send updates to the server/organizer)
* This CL changes the behavior such that a newly arriving event with
a "Busy" status is shown as "No response" in the Calendar, thereby
allowing the user to pick from any of the three possible options.
