Change add client response and correct area ids

[Koseng]

Simplify response when adding a new client. The client does not need to know the WASM internal used IDs for the ClientDataAreas.

Old Response:
{"Name": "MyGreatClient", "SimVars": 3, "Command": 4, "Response": 5}

New Response:
MF.Clients.Add.MyGreatClient.Finished

Change default DataAreaIDs for Mobiflight ClientDataAreas back to the original values. (In the end it doesn't matter, the IDs don't need to be the same on WASM and on external SimConnect client side).

Now in the PR:
SimVar = 0
Command = 1 (SimVar+1)
Response = 2 (Command+1)

Before it was by mistake:
SimVar = 0
Command = 2
Response = 1

That is great. The client does not need to know the WASM internal used IDs

Hi yes,
the relevant identifiers across different simconnect clients in regard to DataAreas is the string identifier.
The mapped numeric ids are only a local optimization on each client and do not matter across clients.
Slowly discovering the wonders of simconnect...
