Preserve all moves in movepicker Simplifies method otherPieceTypesMobile quite a bit and makes it more precise. More precise because capturesSearched list not always contains all processed captures: although extremely rare, it can happen that a 'good' capture get pruned at step 14 and doesn't make it to capturesSearched.
