Tweak futility pruning constants Based on recent improvement of futility pruning by @locutus2 : we lower the futility margin to apply it for more nodes but as a compensation we also lower the history threshold to apply it to less nodes. Further work in tweaking constants can always be done - numbers are guessed "by hand" and are not results of some tuning, maybe there is some more Elo to squeeze from this part of code.
