[WIP] Omnibus of script changes

[bagelbits]

Overview

This addresses #127 and #128. As well as a few other things:

• Drops all of the old scripts which aren't of much use anymore. (I hope I don't regret this later.)
• Adds a package.json file so we can add linting and testing stuff.
• Adds eslint along with the JSON plugin
• Adds a linting command: npm run-script lint
  • This will be useful once a CI gets hooked up.
• A MongoDB nuke and replace script
  • This will be useful once CD gets hooked up.
• Adds heroku.yml
  • This will run the nuke and replace script in Heroku. This is for CD on DB changes showing up in the API

Here's a fun image for your troubles

I want to just hook up Buildkite now since I have access to the settings and I can at least add the linting step.
