Compiles css framework from sass (#1956)

* Compiles css framework from sass

* Adds watch commands

* Copies existing css to sass file

* Moves sass out of static path

* Removes global linter

I wasn't sure how to customize this, and it's not providing a lot of
additional value on top of the domain-specific linters

* Reverts invalid change to dockerfile

* Changes stylelint path

* Remove unused bulma files

* Properly minifies generated css

* Fixes regression in thread display

* rgba function only works with percents for whatever reason

* Hush stylelint

* Removes trailing zeros

* Compile sass in Django

* Python formatting

* Updates linter

* Updates commands

* Adds css-config file
