Update. Caution: this release will format FATFS!

Unfortunately this release will format your FATFS partition again.
A token is now saved in NVS after formatting, so this should be the last time.

The sensor names have moved to a new namespace, so you will have to name them again.

Notable changes:

• Sensors and logging have moved to class FFatSensor. link
• Added Task class. link
• Added LightState class.
• Made webserver callbacks re-entrant.
• ILI9341 code refactor.
