Merge branch 'master' into glitch-soc/merge-upstream

Manually-resolved conflicts:
	.circleci/config.yml
	app/controllers/accounts_controller.rb
	app/controllers/auth/passwords_controller.rb

	app/javascript/packs/public.js

Some content from app/javascript/packs/public.js has been split to
app/javascript/core/settings.js.

Translation strings for glitch-soc's keyword mutes were dropped.

Everything else was mostly “take both”.
