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

Conflicts:
- app/services/remove_status_service.rb
  Conflict because we still handle the direct timeline.
  Took upstream changes, with that one extra function call.
- config/locales/ca.yml
  Conflict because theme names were updated.
  Decided to *keep* the theme names even if they are useless
  to avoid future conflicts.
- config/locales/oc.yml
  Decided to *keep* the theme names even if they are useless
  to avoid future conflicts.
- config/locales/pl.yml
  Decided to *keep* the theme names even if they are useless
  to avoid future conflicts.
