List all the eggs as "available upgrades"

[Former user]

Just a minor improvement... Seeing that other eggs that don't directly change CPS (as Faberge egg and Cookie egg) appear on the available upgrades list (as N/A), I don't see a reason to why eggs like Golden Goose and Chocolate egg should not be implemented as well. It would really help people in knowing how many eggs are left to fully complete the easter set of upgrades, since right now, when I need to see which eggs are left for me, for example, I have to check the "upgrades unlocked list" on CC. I'm pretty sure that this would help lots of people, not just myself. Other than that, keep up with the good work, and thanks for keeping the optimizer up to date, really helpful.
