Use Gulp to compile Sass with Node instead of Compass and Ruby Gems

spicy.werewolf → made their first commit to this issue’s fork.

I find these test instructions incomplete:

* How do I install yarn? Is yarn install sufficient?

* Should I run the commands inside or outside of DDEV?

Regardless of where I run the command, I get lots of warnings:

Warning: In order to avoid variable namspace collisions, we have updated the way to change settings for Breakpoint. Please change all instances of `$breakpoint-to-ems: {{setting}}` to `@include breakpoint-set('to ems', {{setting}})`. Variable settings, as well as this warning will be deprecated in a future release.
    node_modules/breakpoint-sass/stylesheets/breakpoint/_legacy-settings.scss 16:7  legacy-settings-warning()
    node_modules/breakpoint-sass/stylesheets/_breakpoint.scss 41:3                  breakpoint()
    sass/partials/drupalorg/redesign2018/_view-redesign-case-studies.scss 9:3       @import
    sass/styles.scss 95:9                                                           root stylesheet

Warning: 63 repetitive deprecation warnings omitted.

I missed the note about the warnings – I think this is ready for to commit to the "palantir" branch and then we can work on cleanup.

Merged to "palantir".
