Animate the parachute and bubblegum shield

[Semphriss]

I've added a simple animation for the spawning of the bubblegum shield and parachute items.

It's all done in the code, no asset update needed. I've been careful not to affect the internal state of the objects, so it shouldn't affect networking.
