Late night commit. Refactored out "PersonShell" (no longer necessary
with what I know now about the project.) In place, it uses Friends.
Created a simple FriendRequest class because MyFriendRequest doesn't
quite do what I need it to do. Added Outgoing friend requests to Person.
Both incoming and outgoing friend requests use FriendRequest; there's no
real need to separate the two that I can see.
