Enable new eslint rules

[magicmark]

• Enable import/order (to --fix import statements 🎉🎉🎉) (https://github.com/benmosher/eslint-plugin-import/blob/master/docs/rules/order.md)

• Use ES2018 parser and remove old config options (https://eslint.org/docs/user-guide/configuring#deprecated)

Pushing this as an alpha change, since I want to use this, but it might actually cause legit problems:
