If everything goes correctly, nothing noticeable will happen. Changes:

• Remove unique and simple tool kinds
• Specify custom ability sets for weapons that previously created a unique toolkind
• Have agent match on ability set instead of tool kind to choose combat tactic
• Have animations correctly match on ability set for cases where different sets should have a different animation
