Command timeouts

[WebFreak001]

Sometimes commands can start to hang for various reasons (invalid length, stuck in endless loop, child process hung up, etc)

There should be an attribute @timeout(Duration) which sets a timeout for the function. By default every function should have a timeout of 10 seconds.

When a function times out it wont be terminated, it will only send a timeout response (same as error) and if its synchronous it will be moved to another thread (for this they will start in the other thread already and the main thread will block until it times out or the response arrives).

If a timed out function actually returns afterwards it will send the response to message id 0x71 33 00 70 instead (timeout handler)

This will probably fix the occassional auto completion hang-ups on windows
