hero character animations, finally!

- hero walking & idle cycles now rendering
when the chain transitions to a new room or screen, The room rigidbodies (walls) would load up faster than the chain's rigidbodies transform to their new screen location, sometimes causing weird unnatural collisions. So upon each room switch (or screen switch) a quick room cooldown begins. During the room cooldown, the chain link's body types are changed from Dynamic to Static in order to transform them to their location without any weird collision
