- Enemies wander randomly if they can't find a path to a selected attack target.

- Enemies don't select hulls as targets if they're already inside.
- FishAnimController updates the walking animation even if the character is not moving (otherwise the character would just fall down if TargetMovement is zero).
- Eating anim tweaking.
