Bug fixes, usability improvements and Docker
Improvements in this release:

- Fix CORS issues with copy of config between Sprinkler servers. Add CORS violation event.
- Clarify the information in some events, more logical order of events on start.
- Faster discovery.
- Minor fixes in the Configuration web page.
- Add scripts to build a Docker image. More as a way to learn Docker than a real need.
