Built in https/SSL for Radiks server

[stackatron]

This is from the dev survey and could have two components.

A) Include built in https support to Radiks http server.

B) Add documentation specifying that Radiks is designed to be ran behind nginx where https can be handled.

@hstove feel free to mod this with better tasks or an update on this.

I have a different thought about this. I'd like to add a "Deploy to Heroku" button that we can just include in our README. It will give you a free Heroku instance, no coding required, with HTTPS. Then, you can write you front-end app and point it to your Heroku instance. This will also include a free MongoDB database already setup.

I can also create a Docker image, but it requires a lot more work. You'd still need to setup MongoDB or use some hosted service, which is what I'd recommend. Then you need to setup Nginx. It's a lot more work, and the people who want that approach would only really need the Docker image - anyone not familiar with using Nginx would be better off with the Heroku version.
