Cleanup and reorder in qsearch This patch is a simplification / code normalisation in qsearch. Adds steps in comments the same way we have in search; Makes a separate "pruning" stage instead of heuristics randomly being spread over qsearch code; Reorders pruning heuristics from least taxing ones to more taxing ones; Removes repeated check for best value not being mated, instead uses 1 check - thus removes some lines of code. Moves prefetch and move setup after pruning - makes no sense to do them if move will actually get pruned.
