[Design] Replying and Forwarded stamped items.

[Mimi Yin]

I thought of another problem with Forwarding events as messages  
with .ics files attached.

Recipients of this Forward in Chandler will render the Forward item  
as an event invitation.

In the off-change that the Forward-Event is added to a Calendar that  
the Chandler recipient shares with the Chandler sender, how will we  
reconcile the incongruity in Stamps?

The Chandler sender will regard the Forward as a pure message item.  
The Chandler recipient regards the Forward as an event, the Chandler  
sender regards the Forward as a message.

It looks like without more sophisticated support for Clusters and/or  
per-sharee stamps, Forwards are doomed to live in ignominy where they  
could potentially screw up the sender's calendar with multiple events  
that represent the same event, but aren't actually connected to each  
other via UUID or cluster-relationships etc.

However, this is most definitely an edge-case and I'm personally okay  
with noting it as a known issue and moving on to bigger problems.
