Yeah Bruce, U DA MAN! ;)

I now have the alpha-beta search running all thanks to you, however I have
noticed that it no longer can see mates. I find mates by evaluating to a huge
value, could it be that this value is not seen in the AB algorithm, that it is
somehow pruned away?

I can't rule out that I may have a bug, but it does the exact same moves as the
old minimax, except when getting mated, doesn't look like it can see that.

I would like some input on this before I go hunting bugs ;)

Cheers,
Sune
