Simplify Bonus Formula In History Adjustment

Inspired by a discord message [1] from Vizvezdenec, this patch simplifies the bonus adjustment bonus = bonus > 0 ? 2 * bonus : bonus / 2 to a constant addition, maintaining bonus average at around 0 in regular bench. As cj5716 pointed in discord, the constant bonus can also be considered as factoring tempo when calculating bonus, yielding a better value of the move.
