quick-reactions - New feature

[brumm]

Optimistically applies reactions instead of waiting for a slow network request to finish.

This should work anywhere you can react to something on GitHub. Reactions are added, updated and removed immediately. New reactions are inserted in the correct place and will not jump around when the new markup comes in.

Love this. I'm concerned that it will break quickly and painfully, but if it's solid enough I'll just merge it anyway, because we can deal with that via hotfixes.

The concern at the moment is that Refined GitHub is seeing some serious slowdowns in issues/PRs at the moment so I might not be able to merge this or add new features for a while :(

Thanks for taking a look! Let me know if I can do anything to get this into a state you're comfortable shipping. 💪

It's not an issue with this PR, but rather with Refined GitHub itself. I can merge it once I figure out the root cause of this:

• Modifying labels with addon enabled causes browser to hang and pop up warning about a script #7176

because those features also use the selector observer, so I'm afraid that that's what's causing the slow-downs.
