Reduce the defensive abilities of powersuits

This change makes wearers of modular powersuits more vulnerable to damage in the following ways:

- Reducing the maximum armor provided by each piece to 5: This prevents the wearer from achieving high enough levels of damage reduction to be practically invulnerable.

- Reducing the maximum armor provided by each form of protection to 4: This prevents the wearer from achieving full armour from any one form of protection. A combination of measures is therefore required in order to achieve maximal protection. This means that late game, if a player wishes to be fully protected, they must add some weight to their suit even if they have a complete set of energy shielding modules.

- Dramatically increasing the energy consumption per damage absorbed by energy shielding: As energy costs become less significant late game, this change helps to make combat more meaningful with respect to energy.
