redPanther 0aa467cceb populate zeroconf/avahi/bonjour records via json api (#419)
* start of integrating a bonkour service browser

* some experiments

* blub

* bonjour browser via jsonrpc ...

* fix indention

* - make leddevice as component
- extend sysinfo with domain
- add more data for  bonjour browser (e.g. split domain and hostname)

* code cleanup

* add translation

* use component names instead of ids

* fix compile
