Add /banano.json

[stjet]

Hello! I am making a browser extension that lets users tip Banano to the website! It's fairly simple to participate, all you need to do is add banano.json to the root (turtlebyte.github.io/banano.json). The file should be formatted like this:

{"author":"","description":"","suggested_donation":"","address": ""}
(suggested_donation is recommended to be a whole number but it doesn't have to be)

If your not interested, feel free to close the issue and ignore. Also, if you want me to do a PR I can try.

Do a pull request and I'll take a look at it when I can.

Got it. I don't know your banano address though
