Currently, private / direct posts via OStatus from AP compatible instance will be dropped due to failing to fetch AP version.

So this fallbacks to OStatus handling:

* when failed to fetch ActivityPub version
* when status is neither :public nor :unlisted

* Don't process ActivityPub payload if signature is invalid

* Fix style issue

* Guarantee Subscription service first account has proper URL details

Subscription Service potentially could break if the first user suspended
themselves, creating a situation where the urls that populate throughout
subscription service's PuSH request would cause the remote API to throw 503 errors.

Guaranteeing that the first account picked is not suspended prevents this problem.

- Use statuses controller for embeds instead of stream entries controller
- Prefer /@:username/:id/embed URL for embeds
- Use /@:username as author_url in OEmbed
- Add follow link to embeds which opens web intent in new window
- Use redis cache in development
- Cache entire embed

Requires moving Atom rendering from DistributionWorker (where
`stream_entry.status` is already nil) to inline (where
`stream_entry.status.destroyed?` is true) and distributing that.

Unfortunately, such XML renderings can no longer be easily chained
together into one payload of n items.

Commit 9d1f8b9d6a scrolls the columns area
when the route changes since the user is likely to want to see the
rightmost column in such cases.

However, redirection is automatic and does not indicate users' intension.
Do not scroll the columns area due to one.

Add japanese translations for pin_errors.

SerializarbleResource#as_json serializes to Symbol keyed Hash, but current
implementation of LinkedDataSignature expects String keyed Hash.

So it generates broken payload.

For some languages publish translation is long.
