Introduce separate butterfly history table for sorting root moves Idea of this patch comes from the fact that current history heuristics are mostly populated by low depth entries since our stat bonus reaches maximum value at depth 5-6 and number of low depth nodes is much bigger than number of high depth nodes. But it doesn't make a whole lost of sense to use this low-depth centered histories to sort moves at root. Current patch introduces special history table that is used exclusively at root, it remembers which quiet moves were good and which quiet moves were not good there and uses this information for move ordering.
