Added link to my upcoming book, "Responsive WordPress Theming".

Would you mind adding a link to the book I'm writing, "Responsive WordPress Theming"?  It's currently in MEAP (Manning's Early Access Program), and people who purchase it now can contribute comments, questions and suggestions to the author's forum (http://www.manning-sandbox.com/forum.jspa?forumID=872).  The more feedback I get, the better this book can be!

Thanks.
