Move away from Reflux

[magicznyleszek]

Description

The situation is that React is alive and growing, but Reflux is dead since Feb 2017 (wow!). There are no plans for future of the project: reflux/refluxjs#550. We should move to some other library, as we will encounter more problems (e.g. currently we have a problem with npm 7+ dependency mismatch) and will be blocked with upgrading React and possibly other dependencies.

Redux seems to be a good candidate:

@dorey did a research into switching to redux, and it seems we shouldn't go this way. @bufke suggested we should try going the react hooks way, and we will attempt that with new gallery 🤞

Anyone interested in this topic please review my draft gallery rewrite. I'm proposing a very redux-looking style with only react hooks (not actual redux). Now would be a great time to give feedback or suggest alternatives.

FYI: We've decided to move to MobX. We have made few MobX stores already and we are planning to gradually refactor Reflux code into MobX. I'm closing this in favour of multiple different issues, each targeting a singular Reflux store to be refactored.
