Potentially Remove csslint

[carwin]

I don't see a reason to lint compiled code and I misunderstood what was happening when I merged the code. Discuss.

i vote either removing it completely, or replacing with scss-lint (ruby dep). if scss-lint is added to a test command in grunt, only run it if you want to, and have your ci tool run it if you want to.

Late to the party, it's worth trying out the node sass-linter is awesome: https://www.npmjs.com/package/sass-lint

Looks like they've been cranking on it, but I haven't tried it.

If not I vote scss-lint.

If we're not writing a compiler, I don't see why we'd lint CSS. If there's a feature missing from our SCSS/Sass linter, we should try to help fix it there.

For now I've just removed it. I want to avoid using scss-lint because of the Ruby dependency. If sass-lint turns out to be acceptable, we'll put that in. For now let's leave linting on a case-by-case basis until we discover something we can all get behind.
