Support non-JSON .csslintrc format

[fortes]

The typical .csslintrc looks like this:

--errors=import
--warnings=important

This is what the cli csslint expects. Is it possible to support this?

:+1: Very not enough, after switching from Grunt (grunt-contrib-csslint), where rules can be stored in .csslintrc .

This was closed by #17, @SimenB correct me if I'm wrong here. Cheers!

@SimenB on further inspection, it seems we may need to pass a custom parser to RcFinder to support this. Thoughts?

[SimenB]

I'm unsure if Rcloader supports non-JSON? And the warning vs errors part may be tough

It doesn't accept non JSON .csslintrc. It warns that it's not a JSON. It would be nice to have that option because as noted before it the way that csslint accepts options. My use case it's to share csslintrc for gulp and my neomake (neovim) linter. Thanks.
