Replace runningSubStateMachines() with invokableServices()

SCXML allows for different kinds of services, not only other state
machines. We might add support for them in the future. From invoked
state machines you can always get the actual state machine via the
respective property. To make this easily accessible, we make the
invoked services QObjects.
