can you help remove the linter from Travis, and then check that they've got sane SCSS defaults (a la our .unhound.yml...)

And also from #81, wrt https://github.com/causes/scss-lint/blob/master/config/default.yml, there's some configuration options for naming.

We might want to change this to follow Winston's rails_utils (controller is underscored), selectors are dasherised. So a regex for valid identifiers would be in order.

I am not so sure about using underscored selectors in our css. 😕 Nevertheless, I sent in a PR to rails_utils 👉 winston/rails_utils#13

Seems sane to me.
