• Fits CONTRIBUTING.md.

Doesn't build yet, won't be able to work on this in the near future so thought I'd share in case someone wants to pick it up from here.

Build fails with:

   Compiling quasi_codegen v0.32.0
   Compiling bindgen v0.26.3

Things I've tried that didn't seem to help:

• Using fetchgit + leaveDotGit=true + fetchSubmodules=true (submodules contain syntax highlighting bits apparently, haven't looked into that or checked if they're part of the github release)
• including libsass and pkgconfig (see https://github.com/compass-rs/sass-sys/blob/master/build.rs#L41 for what I think is cause of build failure)

It's possible(but I'm not sure, just guessing based on the 'permission denied' mkdir error above) that the build would succeed if the source was read-write instead of read-only, haven't tried this because I'm not sure how to appropriately tell rust where to find the source.

Hope this helps!
