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

[pwest]

I had an additional long-wire DS18b20 probe, and I plugged that in, in place of the Tank probe. It was immediately recognized started working properly including its 'box' display as well as its graph. I'll leave this probe out of the water for a while and see if it is stable. I fear instability issues when I put it in the tank.

I find it curious that the 'Tank Temp' probe worked reliably all day until I enabled the second port--that seems fishy. Both probes had been plugged in the entire time--when I made the software configuration change, the Tank Temp became unstable.

Over the last 10 mins, or so, I've noticed a couple of times where the Dashboard Box display of the new temp display disappeared momentarily.
