Adding a friend feature

Lots of people use pricecharting to keep track of their wishlist's and collections. And I know lots of people who use it and want to share their lists easier. If a friend system is added, you can add your friends and you will be able to go to their profiles and view their wishlist's and collection lists without needing to ask them for a link. This can help compare lists to see what friends have in common or even be used to surprise a friend with a gift from their wishlist.
