Add a suggested set of options for CoffeeLint

[mjrusso]

We should add a recommended set of options for @clutchski's CoffeeLint to the style guide.

Thanks @shanejonas for the idea.

Thanks @mazerte for contributing a CoffeeLint configuration (as per #21).

Leaving this ticket open for the time being, mainly as a reminder to add a little bit of verbiage to the README that references the CoffeeLint configuration.
