RFM2Pi serial baud auto selection

Jeeinterfacer now tries to establish communication at 57600 then 9800 if
unsuccessful. Totally over ridden if com_baud is specified in settings,
only the value specified is used. Disabled the "list" of baud speeds.
Display firmware revision and settings

Uses the "v" command to get firmware version and current settings.
Serves to test the serial port communications and logs the version for
debugging
Amended rfm2pi firmware and settings log

Changed the log message and corrected the logic for displaying pre
RFM12demo.11 version log.
Retained the update advice for the moment may remove or reintroduce
Altered how interfacer name is passed

Interfacer name now passed to class the same way the reporter name is
passed. allows interfacer name to be used sooner, ie in logs during
creation eg serial port opening.
