More tweaks and adjustments

notably making Globals non static but instead a singleton and adding a way to get the singleton instance of blocks using `Block.Instance<BlockType>();`. also makes player sprite rotation for walking scale-based instead of flipping the sprite renderer so that child objects are also affected. This means that the camera had to be moved outside of the player instances.
