Dragon Valley 1.1

I've meant to make these updates for a while, but other games get in the way.

I've updated Dragon Valley with the following:

1. The whetstone treasure now gives you +2 ATK instead of +1.
2. It only takes 5 instances of damage to level up your ATK, instead of 10.
3. I replaced the horse treasure with a parachute, so that when your dragon dies you do not.
4. I made the fleeing rules more clear, to say that you stay in the same hex as the one you were in for combat.
