std.regex wins with 11 votes

[Jesse Phillips]

I wish to congratulate Dmitry Olshansky for not only having his project 
selected for GSoC, but inclusion into Phobos. Absolutely no one had 
objection to this proposal and it received 11 yes votes, myself included.

Dmitry, please merge in the latest master branch and submit a pull 
request so that we can have this great addition in the next release!
