Reworked defense calculations and skill system. Skills now generally gain half of their score from their requisite stat. Defense is now starting out with a base of 1000 and gets another 1000 from dodge, as well as 500 to 1000 from block and parry depending on weapons and shields used. Offense also starts out at 1000, gaining another 1000 from the stroke and 1000 to 2000 from proficiency, depending on weapon quality.
