Lineman plus rails

NOT READY TO MERGE

This PR will be used to take a stab at [lineman-plus-rails #5](https://github.com/searls/lineman-plus-rails/issues/5).

Just pushing this initial setup to give @DerekBriggs a place to get started.

Derek, I realize the repository is a *tad bit cramped*, but hopefully you can make-do with the paths:

* `app/pages/static/lineman-plus-rails.html`
* `app/css/lineman-plus-rails.sass`

You'll see that bourbon is already imported and the basic HTML wrapper is in place. Apologies that the repo doesn't have jade templates for your Slim-loving self.
