The initial implementation of lassooable objects.

The concept is that the player will have a little stick which allows them to tether and move certain blocks.

This will contribute greatly to the puzzle aspect of the game.

Only the base logic is done here so it looks and feels a little rough around the edges.

Additional playersprite animations will be needed to pull out / put away the wand, and previously discovered player squish bugs will need to be addressed more thoroughly

• [ADD] Lassooable object perimeter
• [ADD] Tether to lassoable object by holding space/a
• [ADD] Move lasooable object by moving in a direction while holding space/a
