Add support for async results

Browse source 
Add an async result code and an event to signal the completion.
Use async return values to signal completion of a method and potential
state change.
Add selected format to port update message.
Make it possible to parse into a custom copy of the command memory.
Remove state change events from the elements, we now just update the
state.
Implement async results in the proxy element
