relationships pages shows all relationships in db and sometimes return self instead of related user

If you look at someone else's relationships pages, you are returned a list of all relationships in the db, not just those of that user. Additionally, you are sometimes returned info for the user and the user's relationship. The former is happening b/c of a typo in a variable name (viewed_user vs. viewd_user--missing "e"). The latter is happening b/c the code's comparing using your user object rather than user x's relationship object. Finally, there was some reversed code that returned 404 for real users, the page for uid == 0. A patch is attached.
