Update data calibration: calibration in main loop on boat data values:

- modified code to calibrate affected boat data each second in main obp60task loop;
- removed individual calibration call in all pages
- moved code from BoatDataCalibration to OBPDataOperations
- added DBS and HDT to list of supported data calibration types
- changed output format for wind angles from [-180..180] to [0..360], because negative value are not displayed properly on pages
