Units don't autohunt animals over 10 HP

[historic_bruno]

Since [9046] units tasked to hunt are allowed to hunt any animals but afterward they will filter out remaining nearby animals over 10HP as "unhuntable", which excludes most animals except chickens at 5HP. This is a workaround for AIs, which have no clue what their units are doing if not idle.

It's proposed to remove this hack entirely: let units autohunt everything and fix the real bug on the AI side, by providing UnitAI state info (at least current order and target entity). Then the AI can monitor it's own entities and keep them from doing what it considers a waste of time.

This was fixed in changeset [11055], which went out with Alpha 9. Any remaining AI issues should be reported separately.
