Added dev-docker.sh for developing with Docker

Developing using Docker is now simple and avoids the need to install PHP on the developer's host machine. Common code from `dev.sh` and `dev-docker.sh` has been extracted into a `dev-prepare.sh`. README contains instructions on how to use both dev scripts - which the developer can choose based on their preference.

 - Install PHP7
 - Checkout the project
 - Run `./dev.sh` from the project root
-- Access `localhost:8000` in your browser
+- Access [localhost:8000](http://localhost:8000) in your browser
+
+You can also run the development server using docker:
+
+- Install Docker
+- Checkout the project
+- Run `./dev-docker.sh` from the project root
+- Access [localhost:8000](http://localhost:8000) in your browser
+
+Both the `dev.sh` and `dev-docker.sh` scripts will initialise a configuration based on `data/config.php.example` if `data/config.php` does not exist.
 
 To run remotely, simply install PHP and configure Apache or your server of choice to serve `web/index.php`.
