These were being skipped with `xit`, but we also just added the `unused` task to
the CI server, and it will be caught there. That seems good enough for this,
instead of requiring a full keys check on every local spec suite run.

* Add spec for media controller

Also improve efficiency of the mastodon:maintenance:add_static_avatars task

This change includes:

- Improve the spec coverage for incoming request to the webfinger action
- For requests without an accept header (ie, what a browser might look like),
  return a JSON response.
- For requests with an explicit format of xml or json, return that format.
- For requests using an accept header, return that format.

Also adds failing spec showing webfinger does not return xml, which covers the
issue described in: https://github.com/tootsuite/mastodon/issues/1983

* Add `required: true` option to foreign column

* Fixes NoMethodError

```
> Favourite.new.valid?
NoMethodError: undefined method `reblog?' for nil:NilClass

Sync text for toot form

Un utiliser mal expérimenté pourrait comprendre "retirer les erreurs".
Ici il s'agit d'une suppression pure et simple, pas une épuration/nettoyage.

clear would be translated "remove" instead of "cleaning" Cleaning can be unterstood "keep but clean"

This is necessary for boosting long posts on small screens - see this post for video: https://slime.global/@masklayer/102308

* Open sidekiq and pghero admin pages in new tabs

* Add missing comma

This introduces a new per-user preference called
"Auto-play animated GIFs", which is enabled by default. When a
user disables this setting, gifs in toots become click-to-play.

Previews of animated gifs were changed to display the video play
button so that users can distinguish them from regular images.

This setting also affects account avatars in the detailed account
view, which was changed to use the same hover-to-play mechanism
that is used for animated avatars in timelines.

Fixes #1652

Without setting it, exim will reject the mail with a message like:
rejected EHLO from [10.20.0.1]: syntactically invalid argument(s): {}

* Allow using an SMTP server without authentication (e.g Postfix relay on the same host) by setting SMTP_LOGIN and SMTP_AUTH_METHOD to 'none'
