LMR simplification Unify the "quiet" and "non-quiet" reduction rules for use at any kind of moves. The idea behind it was that both rules reduce at similiar cases in master: one directly for late previous moves and the other indirectly by using a bad stat score which is used for most move sorting and so approximates the late move condition. For captures/promotions the old rule was triggered in 25% but the new rule only for 3% of all cases (so now more reductions are done, whereas for quiet moves reductions keep the same level).
