Using sass and rev without temp files

Hi!

I'm using this plugin in conjunction with gulp-sass, gulp-rev and gulp-rev-replace. And today I'm storing the generated CSS file in a temp folder. It's the only way I found to apply the rev() to the css files.

I have tried to use the additionalStreams option but is not working for me.

Please, can you provide me a example gulpfile without temp CSS files? There is a way or a new feature?

My index.html important fragments:

``` HTML

```

``` HTML

```

My gulpfile.js

``` javascript
gulp.task('sass:dist', () => {
var sass = require('gulp-sass');

return gulp.src(config.sass.src)
.pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))
.pipe(gulp.dest('.tmp/css'));
});

gulp.task('useref', ['sass:dist'], () => {
var pkg = require('../package'),
gulpif = require('gulp-if'),
useref = require('gulp-useref'),
htmlmin = require('gulp-htmlmin'),
uglify = require('gulp-uglify'),
rev = require('gulp-rev'),
revReplace = require('gulp-rev-replace'),
replace = require('gulp-replace');

return gulp.src(['public/views/index.html', 'public/views/signin.html'])
.pipe(replace('@version', pkg.version))
.pipe(useref())
.pipe(gulpif('**/*.js', uglify()))
.pipe(gulpif(['**/*.js', '**/*.css'], rev()))
.pipe(revReplace())
.pipe(gulpif(['**/*.js', '**/*.css'], gulp.dest('dist/public')))
.pipe(gulpif('*.html', htmlmin(config.htmlmin.options)))
.pipe(gulpif('*.html', gulp.dest('dist/public/views')));
});
```

Thanks!
