Close Issue 16 by upgrading to JSHint version 1.1.0 

This commit upgrades the project to use [jshint version 1.1.0][jshint]. In this
version, they've allowed the use of a space before the global keyword.

I've added a unit test that demonstrated this behavior before the
change to the package.json file. I hope it'll be a useful template for
use in other issue testing.
