Conflicts:
- `app/views/settings/preferences/appearance/show.html.haml`:
Upstream fixed a translation bug in the theme selector that is absent from
glitch-soc due to our different theming system.
Discarded upstream changes.
- `streaming/index.js`:
Upstream changed the signature of a function to change its return type.
This is not a real conflict, the conflict being caused by an extra
argument in glitch-soc's code.
Applied upstream's change while keeping our extra argument.
