Interactions: Should display interactor and interaction (repost, star)
Currently only shows original post info, not any of the star/repost info!
- Add configurable header view to PostCell
- Dump list of stars and reposts in as text with wrapping, like "Reposted by: A, B, C * Starred by: D, E, F"
Future, once we have profiles:
- Top view is collection view. Show avatars framed with repost/star lines. Tap avatar to see name and details. Trickier and more visual, but really just the same data.
