Added an Easter BunnyPotato card to the I'M BORED Bonus Page

Feel free to download, print and use from the I'M BORED print-ready stationery page. Hint: it's perfect for including with a gift of the book! You can read it to them while they're lying around in their sugar-induced stupors. Or, um, helping them calm down from their sugar-induced hyperactivefrenzies.
