A few additions for migration to webpack

* Fix issues on paths in build and dev files
* Skip yarn to reduce tooling requirements
* Minify CSS assets in production
* Reduce imports on fonts, hardcode font pieces more. There are problems
  with the font family names. Roboto mixin brings in everything as
  `Roboto-Slab-Bold`, which won't match local font name of 'Roboto Slab'
* Fix the development instance more:
  * Add file watching on reST files
  * Execute build docs command after webpack build

Things I'm still not sure about:

- [ ] The actual JS output, I haven't vetted this yet
- [ ] If woff2 and woff are enough for fonts. The NPM packages are missing other formats
