JSisSexy Link in README links to wrong address

[wmcb91]

In the additional resources section at the end of the README, the link for Javascript is Sexy: Handlebars goes to the handlebars documentation (http://handlebarsjs.com/). I was able to find a handlebars write up on Javascript is Sexy that may have been the intended link.
