Implement Emoji Reactions (Pleroma Extension)

[lambadalambda]

Pleroma supports a reaction system now that is very similar to how likes work. You can see them in action here: https://lain.com/notice/9rX5jNrK28tK19fAwa

I wrote a guide for implementers here: https://git.pleroma.social/snippets/1945

There's not much to do to support it. If you don't want to go for full support, it would be good to at least filter out unknown notification types in the notification display. Currently, emoji reaction notifications display as an empty box.

Glitch-soc is getting emoji reactions soon as well (slightly different API from Pleroma/Akkoma's implementation though, from the looks of it)

This would be a huge improvement for a lot of fedizens, as it is a feature on several of the fediverses' participating community spaces. Let's keep the fediverse decentralized ✊🖐️✊🖐

My current understanding is that Pleroma only supports Unicode emojis, while the Glitch/*key implementation supports custom emojis, though I may be wrong.
