Merge logging to FFat to sensorState class. (#16)

* Started merge of logging to sensorState class.

* Start sensors after setting the time with SNTP.

Some cleanup.

* Remove unused variables.

Save reset reason to file.

Fixed ntpTask stack overflow.

* Fixed getting SNTP sync.

logLineToFile() and resetString() are native again.

* Cleaned up.

* Only format FATFS on first run.

* Fixed fscking script problem. Took a long time to debug.

* Fix last commit.

* Log reset reason to FFat.

* Formatting.
