RemotePerson.followers and RemotePerson.following both implemented in terms of the same helper function.

LocalPerson.followers moved to Person.followers, where it should always have been.
RemotePerson.followers overrides this, just as RemotePerson.following overrides Person.following.

Closes issue #64.
