Use latest version of JSHint

I have updated the jshint.js from [here](http://jshint.com/get/jshint-2.0.1.js). I am not sure if you want to use the [rhino version](http://jshint.com/get/jshint-rhino-2.0.1.js). This is working for me anyway. 

New version has fixed a lot of issues including [function hoisting problem](https://github.com/jshint/jshint/issues/424)
