This adds a docker-compose.yml file which runs the various services
required for a working development instance of StoryBoard (and also
Swift, which technically isn't needed yet). It also provides a config
file which is pre-configured to work out of the box with the services
in the docker-compose.yml file.
It also updates the development installation instructions to recommend
using docker-compose to run the services, rather than installing them
on a machine and configuring everything manually.
