[Feature Request] Aggression updates

[kmfisk]

• Walruses should be PROVOKED
• Macaws and cockatoos should be PROVOKED
• Cassowaries should be PROTECTIVE or AGGRESSIVE. The most dangerous bird in the world currently runs away when hit.
• Chimpanzees seem AGGRESSIVE and approach the player, but do not deal damage(?) PROTECTIVE or AGGRESSIVE would work fine for them, plus pack behavior
• Bald eagle is PROVOKED, so other raptors (condor, harpy eagle, owl) should be too
• Tree frogs should be SKITTISH
• Fiji iguanas should be SKITTISH
• Meerkats should be PROVOKED (but deal very little damage) and have pack behavior
• Platypuses should be PROVOKED and inflict poison on a hit
