Changelog:

• Updated to htheatpump v1.2.3, which now includes several helper scripts (e.g. htcomplparams).
• Added possibility to disable all parameter verification actions (arg --no-param-verification).
• Changed behaviour: No reconnect of the serial connection will be performed for each request,
  because each login() call during a request will automatically try a reconnect on failure.
• Clean-up of setup.py and MANIFEST.in.
