ludic.wildlife (17.6): a fleeing or wary animal goes by the world's way

Browse source 
It sets a target straight away from the threat (40 m when it flees, 20 m when it is wary) and heads for it with wl_head, so the way port takes it round water and cliffs. Where the world gives no way, it still runs straight away as before. way_test now has a flee round the wall's end.
