Description of Problem:
Evolution 1.x used to indicate the number of unread emails in the titlebar
of the application. Evolution 2.x no longer does that. It's really annoying
to have to bring the application to the front to check if I have any email
waiting. 

(yes I could use an inbox monitor applet, but panel space is precious and
having it in the title bar was much nicer)

Steps to reproduce the problem:
1. Receive some new email.

Actual Results:
No indication if new email has been received is in titlebar.


Expected Results:
It should display number of unread messages in my inbox in the titlebar.
