Add 3 tasks for sass in gulpfile.js

I had some issues because of the use of sourcemaps + cssnano together.
I resolved the problem like this :
- The 'scss-for-prod' task to use to create the min.css which is a small file for the prod, but long to compile
- The 'watch-scss' task which is ideal for prod, fast to compile, reload fast and clean sourcemaps

The line :
.pipe(sourcemaps.write(undefined, { sourceRoot: null }))

Is because of this :
https://github.com/scniro/gulp-clean-css/issues/1
and this :
https://github.com/ben-eb/gulp-cssnano/issues/38


So for me, this tasks replace the 'watch-bs'.
