Making Eggs for Docking Station and Docked worlds

Making Eggs for Docking Station and Docked worlds is an official tutorial which runs through the PRAY code needed to make an egg agent for docked worlds and DS-standalone worlds (see Making Eggs for Creatures 3 for how to make C3-standalone egg agents). It is available to read at the CDN, and uses the expressive genome fix as an example of an egg agent for a creature breed with a new genome, but no new sprites.
