Redesign of interactions on content item
Various changes to the way interactions on content work.
- Reply and Share/Unshare are now actions separately from the counters
- Clicking reply expands the editor, but also loads replies
- Clicking replies counter expands replies
- Clicking shares counter does nothing
- Clicking share/unshare action shares or unshares without an extra button
- Each reply now has a reply action icon attached to it. This expands an editor below the reply
This PR does not have the backend change to target replies of replies correctly, this has only the UI side.
