Add indentation lint setting
Move dev commands into npm-scripts
Simplify to a rework plugin; drop autoprefixer

* Autoprefixer >= 1.0 is no longer available as a rework plugin.

* Change the purpose of this module so that it's focus is only on
  providing a bundle of rework plugins that SUITCSS makes use of.

* A dedicated preprocessor module can be used to combine these
  transformations with Autoprefixer and other tasks (e.g., linting).
