alpha v .136 — Arctico Steam update #627340

this update was focused on optimizing the game, resulting in a 10 fps increase on my end. There is still a long way to go before the game gets fully optimized, but this is a good start. Change log: Optimization: The entire logic of the animal AI was revised and optimized. Optimization: Many unnecessary mesh colliders were replaced with box or capsule colliders. Optimization: The looting/interaction system was drastically changed so that everything is handled by a single manager rather than each object having its own manager. Details: now animals do not disappear instantly when being skinned, but rather are slowly dragged into the ground. Tweak: the attack distance of the dogs on offensive mode was increased a little. Tweak: the speed of the dogs when running and following you was increased.
