Update Description:
1. Now both dualism and religions that have adopted the doctrine of Gnosticism can implement the decision "messenger of light".
2. Adjusted some of the requirements for establishing the prestige and piety level of the family legend decision. Now it is only required to reach the fourth prestige and piety level at most.
3. Correction of translation errors.

Update description：
1. Adapted to version 1.5.
2. The dynasty prestige obtained by implementing most decisions is appropriately reduced(500 -- > 250), but the dynasty prestige obtained by some difficult legendary decisions remains unchanged.
3. Revised the need for the "whip of God" legend: the culture of Mazar pillar (such as Hungary) is now allowed to implement the decision, but it needs to occupy Constantinople and Rome at the same time to implement it.
4. Now the AI Lord will try to implement the decision of the family legend.
5. Three new family legends have been added: "Master of the Mediterranean", "victory of the Sisu spirit" and "Eagle of Quraish".
6. Some minor changes in values.
