Smoothen the project before Oldenburg code sharing
Apply the small update that were planned during my stay in Mainz:
- Clearer operator UI;
- Demo configuration directly into the settings on initialization;
- Remove weird old test configurations and ignore them in the future;
- Better error management for missing audio and DAFF files;
- Better light when the lightbulb models are not displayed;
- Correct the lights number of the default configuration.
