- remove some `.gitignore` entries as this is also honoured by `balena push`
- added a step to `scripts/quickstart` to produce a single, flat `docker-compose.yml` after running
- set the compose file versions to `2.0` to ensure only supported terms are used in the `docker-compose.yml` file output
- quoted empty env values as these need to be passed in as blank, and not ommitted
- include the MDNS publisher service IF the domain being used is a .local one
- corrected spelling of macOS in script messages
- move sidecar container source into ./src as per convention
