v4	v5
4	4	* changes HP and food supply of animals according to the calculations in "animal_calculations_3.ods"; it may be noteworthy that chicken have unchanged food supply (40) and sheep now cost 75 food, give 150 food and train time is 50 (50/100/35 before)
5	5	* dps (= total damage / repeat time) changed for some (not all) animals, so now we have: wolf and boar - 15; lioness - 20; lion, tiger, bear, crocodile, rhino and walrus - 25; north african elephant - 30; asian elephant - 40; african bush elephant - 50
6		* armor set to 1/1/10 for most animals (crush armor changed to value of female citizens); 2/2/10 for crocodile, walrus and rhino (hack/pierce armor increased due to though/thick skin); 3/4/5 for elephants (unchanged); 1/1/1 for whales (they got so much hp, that they don't need armor)
	6	* armor set to 1/1/15 for most animals (unchanged); 2/2/10 for crocodile, walrus and rhino (hack/pierce armor increased due to though/thick skin, but less crush armor); 3/4/5 for elephants (unchanged); 1/1/1 for whales (less crush armor due to their size)
7	7	* elongated instead of circle footprints: 2:1 for land animals and 4:1 for whales and sharks; fish footprint adjusted to the actual size of the swarm
8	8	* some cleanup und fix of whitespaces
