add tooltips to show who reacted to your post/comment on main feed

[hamnox]

This needs someone's eyes, it's not optimized for styling.

notes

• had to remove overflow:hidden style on parent div, it was causing the tooltip to not render on thread-view.
  • I tested a long sequence of reacts, it looks like they wrap onto more lines fine.
• also shows tooltip on expanded view, as it's the same function that renders the reactions in both styles. it could in theory take an argument but that feels inconsistent with the coding style.

Reactions with many clicks are clipping at the edge of posts-feed. Possible solution: make a tooltip that is flush with the start of the reactions instead, limit the number of characters it shows.
