Add documentation and easier options for TLS

First ideas were seen in #9 but we should focus on adding a proper termination proxy or focus on exposing Tornado a bit better - e.g to support SSLContext options to be passed along.

Hi there, sorry for digging this old project out. Any updates will be added in the future for this project regarding the WSS connection?

This project is sadly abandoned. Especially as it is really old and unmaintained. But if you're search for something that might solve your issues have a look at django-channels (https://channels.readthedocs.io/en/stable/)
