Robo-Tank v6.0 is Ready - Now v6.5

As this happened it might be good to add that reboot as I really don't think that fix will do anything if it happens again. If you want to leave the fix maybe add a 2nd fix after with the reboot so if it fails that happens. You can call the systemSettings.restart() function. Also have it log before the reset so you know it happened.

but there is an issue. with the forced reboot, if you have an issue with the i2c bus not fixed by the reboot, you will Stick in a boot loop. every time the server boots, the controller starts, write fails and a reboot is made and so on, unlimited.

this makes very hard to connect via SSH because the server is rebooting cintinuosly
