[Chandler-dev] Mail indicator patch committed to trunk

[Reid Ellis]

Thanks to Jeffrey and Bryan, the mail indicator code is now checked  
in. When you have too many email addresses, a "[+4]" indicator is  
used to show there are, e.g., 4 more addresses that are not being  
displayed, plus a tooltip will show all the email addresses.

Many thanks to Jeffrey and Bryan for finding the problem with my code  
(item vs item.itsView).
