[2021] Horde Night feedback - less smart zombies

Is possible. Added to todo list.

They do still look for long paths, but they use reduced block health precision and may quit on the paths, based on intelligence, and do destroy area instead.

They are only going to get so dumb. You build small bases and you limit their choices. Build bigger bases and since distance is a path expense, they will tend to not go the long way. One solution is just adding some totally stupid filler zombies.
