Distribute css/scss files to npm

Hi!

I was wondering if you could provide an CSS/SCSS file that can be included in projects that prefer not to work with the JS version?

FontAwesome v4 does this and I personally think it's a great and flexible way to work with icons.

A developer could just include `feather.(s)css` from node_modules and use it like `` to get the check icon.

Thanks for considering! :)

Start by inspecting the npm package contents and how the JavaScript version is distributed, then determine where the requested feather.(s)css entry should be generated or included. Done means projects can load the CSS or SCSS file from node_modules and use the demonstrated fe fe-check class to render an icon.
