Add more eslint configurations for specific applications

[ojkelly]

A PR is incoming that will add some eslint rules themselves, along with a small config to enable them.

We should also consider creating one or more eslint configurations we can use in our projects, that we could pull in via:

module.exports = {
  plugins: ["@kablamo"],
  extends: [
    "plugin:@kablamo/recommended",
    "plugin:@kablamo/react",
  ]
};
