Title: EntityAnimal does not use the experienceValue of its Parent Class (yet)

I Also added a new variable experienceValueAddition that will mark the
Maximum random Value added to the experienceValue. You may set both
values to 0 to avoid XP Drops by the Animals.

The reason is that I want to be able to change the XP Drop Values to 0 (and also allow other values).
