[Microbit-Python] Micropython random numbers

[David Whale]

There is indeed microbit.random()


Note that there is some evidence of a bug in the runtime random function at
the moment when I use it from Touch Develop, it's not very random, because
it is not seeded (I think).

My Dr Who Daleks game always shoots me on the first two goes, because the
random number sequence is, I think, the same every time.

It would be good if the first time random() was called it seeded it with
the running_time variable so that it was automatically randomized.

David.
