[Gameplay A27] - Han fixes:

- Remove crossbow_training.json from the Han academy
- Adjust the cost of poison arrows and poison blades so that the ranged
upgrade should be the one to cost metal, since ranged units currently
dominate most battles.
- Reduce the obstruction area of rice paddies so that they are easier to
place.
