Address issue #271. Interpret TI information in event 125.

  This TI information, between the words 0xd0000000 and 0xd000000f,
  contains the # of pedestals, the time interval between scaler events
  the event interval between synchronized scaler events and the
  prescale settings.  Two versions of this block of data are supported,
  version one is mssing the scaler interval values.

  Nothing is actually done with the information found in event 125, but
  a summary can be printed with the method THcConfigEvtHandler::PrintConfig()
