and so was just annoying
2. Get rid of all existing ESLint errors.
2a. Turned off `react/display-name` because I couldn't figure out how to
make that wrapped component have a display name. If anyone can figure it
out, that'd be great, because that makes things nicer when using the
React debugger.
2b. The part where it says `plausible()` is undefined in `app.js` is
bothering me. I disabled the check because I can't figure out where that
actually comes from to put in the proper import.
2c. Told ESLint we're using Babel.
3. Added `npm run format` and `npm run lint` commands.
