[PATCH] Change the loot XP of gaia animals

[mimo]

Currently, all gaia animals have a Loot of 10 XP points, except elephants which have some custom values (from 50 to 75 depending on the elephant). We should have a different Looting XP points for i.e. a chicken or a lion. See the attached patch which remove the Loot for domestic animals, and put different values for skittish or agressive animals.

update the XP loot points of animals, fixes #3701, and remove the outdated and not used elephant template

The commit looks good to me, but shouldn't skittish animals like deer / giraffe / zebras yield more than 5 XP (how about 10 or 20?), considering that you would need to kill 20 deer with a single unit to promote it, which will basically never happen?

[mimo]

I don't see hunting of skittish animals as a way to promote units, but only to give it enough points such that it will be promoted with the first enemy killed. That said, i agree that 5 is maybe too small and i've nothing increasing it back to 10 as it was before.
