Announce activities should be streamed back to their creator
Currently, if a user reblogs a status, the only people notified by the user
stream topic are those listed in the recipients
section of the activity (as described by User.get_recipients_from_activity\1
)
When a user reblogs a status, it should appear on their stream as well
Not entirely sure of the best place to implement this, but i'll poke around nonetheless
