Add a word API

[ZeroDayOwl]

I have added an API that fetches one random word every time a session starts. Guess it would be hard to beat this game now!

The API you are using, what license does it provide? How do we need to give a reference to it? Please consult the API documentation and comment here. If possible you can always make a second commit making those references but I'll merge it nonetheless... Good commit!

There isn't any specific API documentation or license that could be consulted, but in the website it's hosted, the owner said not to use his site for production uses. So I guess we need to host the API ourselves to use it, since the source code is already given there.

Hosting a scalar API for a minigame is overkill. Can you look for any other similar APIs? There should be plenty around. Make sure to check these:

• The owner permits for free use of the API with reasonable limitations

• The server is stable and guaranteed to stay up for it's reputation (I was thinking something like Wikipedia or Wikihow API, you can also take the data from any public dictionary API if you find them)

The branch can be merged if we can find a better suited API server, not a proof of concept project hosted in heroku. Thanks!

Sure, I would look further to find a better suited API server for the game.
Thanks for approving the PR!
