Add Docker-compose file for windows compatibility (alshedivat#875)

This file makes it easier for windows users to use docker. (Closes alshedivat#829)

Previous to this commit, those who used Windows had to install Ubuntu
inside windows (via WSL) and run our commands. Now they can run it by
just typing `docker-compose up`.

> The main problem was that `./bin/dockerhub_run.sh` command was written
with `Bash` in mind and you had to change it a little bit to make it
compatible with windows `Powershell`. We shouldn't have two scripts.
This is why adding a `docker-compose.yml` file is necessary.
