Soldier Shield Revamp

Soldier shields now have base 0 armor and 0 defense.

Jonas shields go up to 2 armor (previously 4).

Remember, armor is now solid 100% instead of a random 33-100% roll.
These items being free 2-4 armor would have been way too strong. Jonas
shield being = 2 instead of 1-4 locks it in pretty close to where it was
before.
