Improve move order near the root Current move histories are known to work well near the leaves, whilst at higher depths they aren't very helpful. To address this problem this patch introduces a table dedicated for what's happening at plies 0-3. It's structured like mainHistory with ply index instead of color. It get cleared with each new search and is filled during iterative deepening at higher depths when recording successful quiet moves near the root or traversing nodes which were in the principal variation (ttPv).
