[WIP] Replace scss-parser with gonzales-pe

[phlmn]

Hey,

I've replaced scss-parser with gonzales-pe to increase compatibility with certain SCSS features, most likely varargs. This fixes #18. Two tests are not running yet, maybe you've an idea for that.

I also added an editorconfig file.

Cheers,
Philipp

@phlmn thank you, I also noticed the varargs issues, sass has a pretty a huge set of features to cover. Unfortunately I have been knee deep in all kinds of things the last weeks so haven't had time to look into it. Will check this alternative parser out tonight and see if we can iron out the remaining issues for a new release.

I just had some time today to test the gonzales-pe-version, this also fixes my issue with scss-parser. Finally I could import my whole module tree for sass-extract.

Thank you @jgranstrom for putting the plugin together, and thanks for @phlmn for creating the gonzales-pe version of it. Hope it will be included to the plugin. :-)

@phlmn @bencergazda this and more has been included in the latest 2.0.0 release. Thank you for your work with the parser!

@jgranstrom Awesome! 😊 Still has problems with Bootstrap 4.0.0-beta.2 but that's probably a syntax error in their code...
