Adjust Nonobar Favorites on Game Deletion

When a game gets deleted from your Nonobar (and to a lesser extent, your favorites), it would be nice for a message to appear in your news to the effect of "Hey, remember this game that you used to play? It's gone now."

If a game is deleted because there's a duplicate, it would be nice for the Nonobar and favorites to switch to the version still on Nonoba. If this is done, you probably don't need to send a message alerting users to a deleted game.Score is 5
