Adjusted leveling to accomidate different play styles.

Version 15 was mostly updating graphics, adding some new weapons, the battle axe and ancient sword, and displaying your helmet and armor in combat.

Version 16 now gives experience for taming, threaten or negotiate. If you level up on purely these methods, meaning you have done no combat, then your stats will will reflect that. Spirit and Charm go up instead of Endurance and combat skill. You can choose to level up with combat, which will lead to increased combat skills and a tougher character. Hopefully this will allow the player to progress the way they want their character to be. I also adjusted healing and the counter attack. Healing is now more effective the higher your spirit is. It may need refining.
