Bump package versions for gulp-sass and phantomjs-prebuilt

gulp-sass is bumped for node v7.10.0 support.
phantomjs-prebuilt is bumped past 2.1.8 to solve installation failure
when TMPDIR is not set.

Note that one dependency is still unfixed and thus needs a workaround:
karma-runner/karma-phantomjs-launcher#200

 ### ChangeLog
 
+* 0.8.2: bump gulp-sass version for node 7.10 support.
 * 0.8.1: Some jade->pug fixes. beware that with jade-pug the default extension is .pug so extends "layout" will look for layout.pug
          You can just rename your layout file or extend with explicit file extension
 * 0.8.0: upgrade dependencies. (gulp-minify-css -> gulp-clean-css,  gulp-jade -> gulp-pug). Fix node dependencies to make yarn work.
