`renderPass2` is looping over every entity for every frame, this updates the method so it only evaluates each entity once.
Adds ability to query by rectangle or circle.
* WIP: Add support for missiles
Break AnimatedEntity into two parts to support single and composite animations. Summon misssiles on right click.
