Improved -> Broke -> Fixed basic_python AI

In the first place, should have probably actually tested this AI
It was calling "move" with only 3 arguments, when I added a fourth one (multiplier)

In the second place, added storing of more information by InterpretResult
Also rewrote the code to make it much clearer when I got tired of retyping "self.board[p[0]][p[1]]" every second line...

Of course rewriting the code was a bad idea, and caused many stupid errors.
But it should be fixed now...

Since asmodeus and other python AI inherit directly from the BasicAI class in basic_python, it kind of needs to work.
