* handle UI controls initiated in the UI, and "core-ui-control" that handle UI
* controls initiated in the core. The reason for hawing two services is that
* some of the UI controls expect the core to respond with some data. The
* simplest way to differentiate core commands from core responses to the UI
* commands, is to have two separate services: one sends commands only, and
