Add SASS/SCSS compile options for output Style as expanded, indent Type as space, and indent Width of 2 spaces

  var sassOptions = {
    outputStyle: 'expanded',
    indentType: 'space',
    indentWidth: 2,
    linefeed: 'lf'
  };

  return gulp.src([paths.scss.src])
    .pipe(sass(sassOptions).on('error', sass.logError))
    .pipe(postcss([autoprefixer({
      browsers: [
        'Chrome >= 35',
        'Firefox >= 38',
        'Edge >= 12',
        'Explorer >= 10',
        'iOS >= 8',
        'Safari >= 8',
        'Android 2.3',
        'Android >= 4',
        'Opera >= 12']
    })]))
    .pipe(gulp.dest(paths.scss.dest))
    .pipe(browserSync.stream())
