Carimus ESLint Config for Web

The prettier config used by Carimus web projects. This config is a good base config for any JS project that uses eslint.

Extends eslint-config-standard which is the eslint config that enforces standard JS code standards. Read more about those here.
Uses babel-eslint parser with support for modules and experimentalObjectRestSpread.
Includes the eslint-plugin-jest plugin and configuration for e.g. Jest globals.
Includes the eslint-config-prettier preset config in order to unset any rules that would conflict with prettier.
Some minor rule overrides that:
- ban var
- ban console statement
- ban undefined
- require camel cased variable names
- some other minor tweaks built-up over time across projects to promote healthier code

TODO

[ ] For React projects, there will be a separate config that includes the react-specific stuff that extends this one.
