Instance improvements

* Better event handling by binding class methods
* Removing event listeners when disconnecting
* Closing GRPC connections savely
* Removing connector instances savely
* Better handling of shutting down the Inexor Core process 
* Load instance configuration from TOML
* The logging of each connector can be configured separately
* Tree nodes can be removed even if read only
