Fix for incorrect version dependency syntax

As far as I can tell you've used caret (`^`) instead of great than (`>`) for "more than" module dependencies which leads to the following error:

``` shell
npm ERR! Error: No compatible version found: coffeelint@'^1.0.2'
npm ERR! Valid install targets:
npm ERR! ["0.0.1","0.0.2","0.0.3","0.0.4","0.0.5","0.0.6","0.0.7","0.1.0","0.2.0","0.3.0","0.4.0","0.5.0","0.5.1","0.5.2","0.5.3","0.5.4","0.5.5","0.5.6","0.5.7","0.6.0","0.6.1","1.0.0","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6","1.0.7","1.0.8","1.1.0"]
```

I've updated `package.json` to correct this.
