Do more futility pruning in qsearch This patch introduces a third futility pruning heuristic in qsearch. The idea is that the static exchange evaluation is much worse than the difference between futility base and alpha. Thus we can assume that the probability of the move being good enough to beat alpha is low so it can be pruned.
