Introduce static history
The idea of this patch can be described as following: we update static history stats based on comparison of the static evaluations of the position before and after the move. If the move increases static evaluation it's assigned positive bonus, if it decreases static evaluation it's assigned negative bonus. These stats are used in movepicker to sort quiet moves.
