Catch JSON.parse error

[bdeitte]

Catch JSON.parse error so that unhandled errors aren't thrown. With this addition, you can handle the errors in your stream like this (making sure the on error handler is directly after the pipe to jsonSass).

  fs.createReadStream(configPath)
    .pipe(jsonSass({
      prefix: '$config: '
    }))
    .on('error', function(e){
      console.log('ERROR: ' + e);
      done(e);
    });
