Pymodbus 1.5.0

[dhoomakethu]

• Improve transaction speeds for sync clients (RTU/ASCII), now retry on empty happens only when retry_on_empty kwarg is passed to client during intialization

client = Client(..., retry_on_empty=True)

• Fix tcp servers (sync/async) not processing requests with transaction id > 255
• Introduce new api to check if the received response is an error or not (response.isError())
• Move timing logic to framers so that irrespective of client, correct timing logics are followed.
• Move framers from transaction.py to respective modules
• Fix modbus payload builder and decoder
• Async servers can now have an option to defer reactor.run() when using Start<Tcp/Serial/Udo>Server(...,defer_reactor_run=True)
• Fix UDP client issue while handling MEI messages (ReadDeviceInformationRequest)
• Fix Misc examples

eek… Been pulled to do something else while the code I wrote is in user acceptance test which could last a few months. Due to horrid time pressure, I have no time to test the new release. I do apologies as it's a shitty thing to do to you when you have been nothing but kind.
