misc/dashboard/codereview: show first line of last message in thread

Browse Source 
This line helps me to tell whether the CL is waiting for me or I'm waiting for the author.

Also:
 - vertical-align table cells so buttons are always aligned with CL headers.
 - add email= to show front page for someone else.

 Demo at http://rsc.gocodereview.appspot.com/.
 Until this is deployed for real, some recently changed CLs may be
 missing the 'first line of last message' part.
