Need resourcePath in custom importer

[jameslnewell]

Because stdin is the value of prev in function (url, prev, done) my custom importer can't load files relative to the SCSS file @importing another SCSS file.

Could the importers be wrapped something like this?

sassOptions.importer = sassOptions.importer 
  ? [].concat(sassOptions.importer).map(function(importer) {
    return function(url, prev, done) {
      return importer(url, prev === 'stdin' ? resourcePath : prev, done); // <== replace 'stdin'
    };
  }
  : []
;

That looks like a good idea! Can you create a PR + a small test-case for it? Just mention me in my PR and I will merge it asap.

I can't be sure, but I think this breaks this inside of the custom importer. I'm not sure if that's a problem that can or should be solved in the importer or not, but see here for context.

return importer.call(this, url, prev === 'stdin' ? resourcePath : prev, done); should fix that I think
