Troubleshooting and ...
- More i18n
- Easy use of mutual exclusion in JsonAPI with QMutexLocker
- Smoothing type "linear" hidden in the WebUI, because there is currently only one
- Message forwarding implemented again
- For compatibility to home assistants and other remote controls, "activeEffects" and "activeLedColor" has been added to the JSON-RPC
- FlatBuffer clear now the Priority on disconnect
- The information "available V4L2 devices" is now only displayed if the device list is not empty
- LED device "PiBlaster" excluded from OSX build
