Resolution Mechanic

• Changed the stress die mechanic to increase the chances of reducing the dice pool
• Added a dice pool limit based on wounded and broken conditions
• Updated resolution mechanic to remove the wounded and broken conditions and remove environmental aspect from the equipment statement
• Minor change to the experience gain mechanic

I wanted to streamline the resolution mechanic and remove an odd interaction between the wounded/broken conditions and the dice pool. These conditions now have a more direct impact on the dice pool, somewhat similar to the way Ironsworn's debilities affect momentum.
