Known issues
* The animations always start from the first animation when the play button is hit.
* The bounding box will still deform as if the model is animating while the animation is stopped.
* Player cocking weapon sound on startup
* Player assets load on startup. This makes the startup longer than it should be.
* Unchecking or deleting an animation in the sequence will continue to play that animation until it finishes.
* Animations do not blend together
