Auto-subscription: little less verbose
Summary:
When the user "Mrs. Kitten" adds or remove "Mrs. Kitten" as Subscriber,
usually these messages were generated:
Mrs. Kitten added a subscriber: Mrs. Kitten. Mrs. Kitten removed a subscriber: Mrs. Kitten.
This was a bit like the Spiderman meme self-pointing Spiderman.
After this change, these beautiful messages are generated instead:
Mrs. Kitten subscribed. Mrs. Kitten unsubscribed.
