animal DPS balance

[Palaxin]

This is the second part of #3778.

Having a closer look at gaia animals' attack, there are many strange things to observe. E.g. a wolf nearly has triple the DPS² of a lioness. Lions are also pwned by boars, the crocodile gets smashed by a wolf and even the big rhino doesn't do more damage than wolves.

	attack
animal	hack	pierce	crush	RT1	DPS2
lioness	15			2	7.5
lion	20			2	10
boar	12			1	12
crocodile	30			2	15
wolf	10	10		1	20
snow wolf	10	10		1	20
bear	20		20	2	20
rhinoceros	20		20	2	20
tiger	30	20		2	25
walrus	15	10		1	25
North African elephant	20	20		1	40
Asian elephant	22	10	18	1	50
African bush elephant	25	10	20	1	55

Below is a first proposal how to adjust the values. If there are no complaints, I will create a patch based on that. I rounded all values to multiples of 5 and assumed that hack attack corresponds to paws and pierce attack to teeth or horns. Crush attack is added for very large animals. I assume the repeat time is roughly adjusted to the animation but I will still check for possible changes there. Note that the average DPS of all animals nearly remains the same (from 24.6 to 24.2).

¹ repeat time ² damage per second = (hack attack + pierce attack + crush attack) / repeat time
