commit 20eba6f

Add boosts, likes and reacts to actor's people page

Show in an actor's page anything that the user could have seen from
actor in timeline or notifications, namely:

- posts by actor (use get_atto to identify the actor)
- boosts by actor
- user's posts with likes or emojireacts by actor

That said, in this view, only the latest boost is shown for a post, so
it might not seem like the boost is by actor.  Likes and emojireacts
aren't even shown, so the reason why a post appears might be puzzling.

Use timeline_simple_list, since we don't show entire conversations,
and we want to identify all posts with actor's interactions.

Saturate show at max_timeline_entries, so that we don't silently skip
entries.
