This patch introduces extension for captures and promotions.
Every capture or promotion that is not the first move in the list gets extended at PvNodes and cutNodes.
Special thanks to @locutus2 - all my previous attepmts that failed on this idea were done only for PvNodes - idea to include also cutNodes was based on his latest passed patch.
