Animations

Animations are added in. See the Level: AnimationTesting.

Still needs tweaking.

Jumping animation not consistant.

Walking animation playing by default instead of idle after walking.

colliders might need adjusting on the animation model.

No falling animation included just yet. Need more testing with the
jumping animation.

Location of the Box being picked up is too far out - might be due to
scale.
