Subject: [PATCH] Notify replies and repeats

This is especially useful for partial federation with remote accounts
that are not fully OStatus-enabled but support a pingback protocol.
Such accounts will still be notified of replies and repeats of their
content even without OStatus support, thus adding to the federated
universe.
