Simplify condition for assigning static-eval based bonus for quiet move ordering and simplify bonus formula. Due to clamping the bonus to relative low values the impact on high depths is minimal, thus the restriction to low depths seems not necessary. Also the condition of movecount in previous node seems to be not determinant.
