Adds docker-compose configuration

[insuusvenerati]

This PR will add a folder called .docker which contains files that will create images used in docker compose to spin up a full Pathfinder stack.

Some configurations have been changed so that the services communicate with each other properly in a docker environment. Note the changes in config.ini which point cache data to the redis container and changes the session cache to use the php handler.

Environment.ini was changed to set the socket host to the websocket container.
Readme.md was changed to add docker instructions.

The websocket was added as a submodule pointing to my fork. One change needs to be made to the tcpHost because it defaults to 127.0.0.1 which is not available outside a container. This can obviously be set using the --tcpHost argument.

I would recommend merging this into a different branch because of the config changes but im new to doing PR's so if there are any recommendations i'm more than willing to make this work. I spent 8 hours getting it running stable so what's a few more to make sure it's viable as a good contribution.

I'm also in slack as stiforr if you have any questions.

I'm very interested in this. Is this going to happen?

[insuusvenerati]

Might have to revisit this. Could do without manning changes to the app

I am learning it (as well as Git in general) and am looking at modifying this Dockerized version now: https://github.com/KryptedGaming/pathfinder-docker

I've been reviewing the files and I see nothing nefarious but would prefer native support using MariaDB and Traefik for the native docker support and built-in Let's Encrypt functionality.

You can also find some more Dockerfiles in my repo https://github.com/tralafiti/pathfinder

Sadly didn't have time to move this into it's own repo / publish pre-build packages and it still uses mounts instead of volumes but it's running solid on my system including Maria, Redis, Websocket etc.
