FixLayout_Header_LogView
Bugfix header EEPROM layout:
Batterycharge was added to the header memory structure which is also used to store data in EEPROM => Information read from EEPROM which were created before the change was not read out correct.
To avoid this problem and to keep the layout consistent a not used data item has been changed to the new batterycharge value
