Created new Skill class (lacking boolean : checked and encapsulation methods) to support and enforce uncheckable skills (such as Cthulhu Mythos, Sorcery, and Status).
Altered old Skill class to be CheckableSkill class (which subclasses the new Skill class).
Added ArrayList<Skill> combatSkills field and encapsulation methods.
Revised to take Skill-CheckableSkill split into account.
Revised baseSkillSet and baseCombatSkillSet to reflect character sheet (removed non-standard specializations to separate arrays, e.g., artSpecializations[], and added notes about Science and Language (Own)).
Altered personality system for greater flexibility. Partially implemented pickPersonalityType(); stopped at handling for skill (any) options.
