[Lint] Update linter to use babel-lint and lint JSX/React directly

- Upgraded eslint
- Installed babel-eslint so that we can parse JSX and ES6
- Installed eslint-react-plugin so we can lint JSX directly w/o a transform
- `no-comma-dangle` was replaced with `comma-dangle`
- `space-unary-word-ops` was replaced with `space-unary-ops`.
