We don't have releases, so it don't make sense to mention.
On the other hand, a lot of our code is from upstream, so encourage people to
check whether it is a bug in glitch-soc or upstream.

Conflicts:
	.circleci/config.yml
	app/controllers/authorize_follows_controller.rb
	app/javascript/packs/public.js

Moved new stuff from packs/public.js to core/public.js.
Added appropriate use_pack in new controllers.

This includes clicks on hashtags, mentions, display names and media in the
timeline; and usernames in reply-indicator, detailed status, and the boost
modal.

* Add “bundle clean” suggestion from CircleCI doc

Cf. https://circleci.com/docs/2.0/caching/#bundler-ruby

* Use workspaces instead of caches for ruby gems

Cache are not guaranteed to be available, while the test jobs *require* their
depencies to run. Workspaces are thus more suitable.

One downside is that the order of workspace layer additions need to be
deterministic, which is why install-ruby{2.3,2.4} now depend on
install-ruby2.5.

* Add remote interaction dialog for toots

* Change AuthorizeFollow into AuthorizeInteraction, support statuses

* Update brakeman.ignore

* Adjust how interaction buttons are display on public pages

* Fix tests

Merge upstream changes

* Implement Undo { Accept { Follow } } (fixes #8234)
