Add prettier to auto-format code?

[pdehaan]

Here was my local config, although the indenting is a bit different between ESLint and Prettier, so I think we'd need to disable the indenting rules in ESLint.

"format": "prettier 'src/**/!(kinto-http|quill|quill.snow).{css,js}' --single-quote --write",

And here's my output (showing the processed files):

➜  notes git:(fix-eslint) $ npm run format

> notes@1.0.0 format /Users/pdehaan/dev/github/mozilla/notes
> prettier 'src/**/!(kinto-http|quill|quill.snow).{css,js}' --single-quote --write
