Async animals alert

[still222]

Vanilla uses (mostly) needs.food.TicksStarving to determine if animals are hungry/starving. Which in async results in constant warnings, when viewed from another, higher tick map.

Meanwhile vanilla humanlike trackers use needs.food.Starving, no idea why it wasn't done to the animals in the first place.
The most non-intrusive way I could come up with, was using postfix to filter the results and ensure animals actually hungry.

There is a separate bug for (async?) alerts, which results in them "jumping" around when hovered with a mouse. Not sure what causes it, but it's not this commit. With this commit if you see the alert, that means 100% there are starving animals, though sometimes (dont know exactly when or why) to get correct, non-jumpy tooltip, you have to find a correct map first. Without this commit alert will always show, sometimes jumpy, sometimes not, but they will be wrong most of the time.

I've tested it as an external patch, cannot build real multiplayer dll for some reason.

If you can test it would be cool - host async server with 2 maps, have some pen animals (that have food need) in a pen and drift another map at least 30000 ticks (half a day) ahead.

Without commit you will see "Hungry pen animals" and "Animals starving" alerts when viewed from another map, with commit you should see them only if any animals have their need.food <= 0f.

When not in async postfix does nothing to save on iterations.
