David Simcha, Tomek Sowiński, and Jens Mueller approved as GSoC 2011 mentors

[Andrei Alexandrescu]

We have three more mentors joining: David Simcha, Tomek Sowiński, and 
Jens Mueller.

(I'd already mentioned David's approval but only as a reply to another 
message, an oversight that this attempts to fix.)

David, Tomek, and Jens bring tremendous value and broad expertise to our 
mentor ranks. Thanks to all for your participation!
