Issue:
Sass Syntax - Clean import paths issues
There are issues with the `clean-import-paths` rule when using the sass syntax as it's valid syntax to use without quotes. See guide http://sass-lang.com/guide

This in turn breaks the way we're detecting strings and validating them so a new way will need to be thought up.

Pull request description:
Hotfix master - Fix Sass syntax issue with clean-import-paths rule
clean-import-paths doesn't work with Sass syntax. This fixes that issue.

Fixes #179
