Robo-Tank v5.10 is Ready

[Rob F]

Ok, I think I know what will solve the 4.2 issue if you want to try this.

In the display and controller sketches search for "Serial1." without the quotes and change everyone you find to "Serial2." without the quotes.

Then upload both and 4.2 should startup with display connected. If that works do the same with v5.12.

I don't really see the connection to v5 and this but it must be the same thing as everything else checks ok.

I have to leave for a few hours, let me know how it goes, if you need sketches I will send then.
