Added coffeelint support

Please let me know if there are any styling updates, or other such changes. I originally intended on using the broccoli-coffeelint library but it was triggering a bunch of errors so I used that as reference and rolled my own.
Also, some space on either side when using colored backgrounds look nicer.

```js
// Like this (chalk adds spaces between strings)
console.log(chalk.bgYellow.black('', error.message, ''));

// Or like this
console.log(chalk.bgYellow.black(' ' + error.message + ' '));
```

I'm not sure what the recommended way is with chalk, but it does look nicer:
