Extend captures and promotions

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.
