Quick install instructions are insufficient

[jc-harrison]

As of #610, docker-compose.yml requires development_environment to be sourced (or the environment variables otherwise set) before running docker-compose up. The quick install instructions have not been updated to reflect this.

Rather than instructing a user to download and source development_environment before docker-composing, it would seem preferable to provide either a bash script which would set the env vars, download the compose file and spin everything up, or a demo docker-compose file in which the env vars are already set (this links in with #614).

While we're on the subject, we should also review the dev and production install instructions, to ensure they are correct and sufficient.

If it weren't for the build sections in the compose file, one could simply do this:

#!/usr/bin/env bash

set -a
source /dev/stdin <<< "$(curl -s https://raw.githubusercontent.com/Flowminder/FlowKit/master/development_environment)"
export DOCKER_FLOWDB_HOST=flowdb_testdata
set +a
curl -s https://raw.githubusercontent.com/Flowminder/FlowKit/master/docker-compose.yml | docker-compose -f - up flowdb_testdata flowapi flowmachine flowauth query_locker

And get people to curl-exec that.

Should also review the instructions about Setting up a development environment - possible that the changes in #610 have affected those too.

Given #693 and #694, we happy to close this after #713 is merged?

I'm happy to close this. There is further cleanup / rewriting to be done, but this should be tracked in separate issues.
