Move from CSS to SCSS (#86)

* Rewrite existing style.css with sass

* Add "uses-rst" class for pages that use rendered RST

This replaces the previous method of just listing
every page in the sass

* Remove old debug print

* Mixins and error pages

* Newly built CSS

* Add SASS cache to .gitignore

* New error SASS

* Slight changes to error template

* Add UIKit SCSS to repo

This includes the LICENSE and our customizations, which
makes life way easier for contributors

* Reorganize sass folder; your watchers can avoid uikit now

* Sass folder should be called scss

* Change variable names

* [SCSS] Linting

* Fix scss_lint gem name [ci skip]

* [SCSS] Now you can compile with just Python!

* Temporary hack to make the wiki editor taller

* [SCSS] @jchristgit

* [SCSS.py] Require specification of include dir to simplify the SCSS imports

* [SCSS] All inline styles have been removed

* [SCSS] Update UIKit theme to import from our variables

* [SCSS] Remove extra newlines in errors/_common.scss
