Re: xPL Lib events

["Mal Lansell" <mlansell@xxxxxxxxxxxxxx>]

According to the xPL docs, reconf and option type config items can be
changed at any time, so they should be updated whether the device is
awaiting configuration or not.

That's the behaviour in my C++ code - any config.response message received
results in the values in the config items being reapplied in the app.
