Subject: More on HG Friends. Added Delete(string, string) across the board.
 Added security to friendship identifiers so that they can safely be deleted
 across worlds. Had to change Get(string) to use LIKE because the secret in
 the identifier is not always known -- affects only HG visitors. BOTTOM LINE
 SO FAR: HG friendships established and deleted safely across grids, local
 rights working but not (yet?) being transmitted back.
