Reverted changes to time format. Added a 'SENSOR_DETAIL' and 'SENSOR_COMPLETE" logging options. 'SENSOR' should now be used for high level information, 'SENSOR_DETAIL' should be used for medium level information, and 'SENSOR_COMPLETE' should be used for low-level information. If SENSOR_DETAIL logging is turned on, then SENSOR logging is also turned on. If SENSOR_COMPLETE logging is turned on, then SENSOR_DETAIL and SENSOR loggin is also turned on. All three of these levels use the 'SENSOR' prefix when outputting logging lines.
