Remove the type of moved piece from the evasion capture movepick formula In the move generation the moves are generated in the order pawns, knight, bishops, rooks, queens and king. This follows increasing type_of(pos.moved_piece(m)) term, so in master a capturing was sorted after a capturing rook if the same piece was captured in evasion. Because we use a stable sorting method (stable means the order of elements with the same value are not changed) and generate the moves in the above order we do'nt need the removed term.
