Datalog 3.0.0.0 release

Demo of Datalog 3.0.0.0 went well, with no last minute hitches. Only need to include a license file and it's done. I can already think of improvements to make, such as encapsulating more code into classes, and also more improvements that need to be made, such as better comms control, and reduction of the processor overhead. But for now, it has the green light to ship!
