Changed icon to new RIT-trademark-free one

Replaced the icon with a more generic tiger pawprint so that I'm not using an RIT trademark, so that I'm prepared for the first App Store release. Also added information about where menu information is being sourced from on the about screen, and fixed a bug where vegetarian/vegan/no beef/no pork toggles would not be written to UserDefaults.
