Get it while it's hot ;)

http://www.chessbrain.net/beowulf/

I think I fixed all the huge problems with previous releases, for example
whatever it was that caused a drop of around 100-150 ELO for the last WBEC
Ridderkerk tournament ;)

I've also merged together the standard code and the parallel search algorithm
that is being used for Chessbrain.net. I'd leave that well alone if I were you
;)

Let me know of any bugs/errors/omissions/total cockups please ;)

Cheers,
Col
