Tyler Breland: Overlord solution

You must have node.js installed to run (LOL!)

Once you have it installed, do:

```npm run all```

To install deps, run the tests and start the server.


On this and the previous feature files: you've got a single happy path test, but what about other cases? What happens when I enter the wrong code? What happens when I try to enter a code for an exploded bomb? It's important to cover those cases as well.
