Animation! (sort of)

So I finally made some modifications to the code. I made it so that the potions animate (up and down as if they're floating) now. This makes me want to add a generic shadow sprite to draw below them just for better looks. As it is, the current sprites from Rime has shadows built in that move with the potion up and down, so it looks like they're sliding across the floor. Still, i think it's a step in the right direction. And with new images being potentially added soon it gives me fresh motivation to work on these things.
