* Cache relationships in API

* Fetch relationships for search results in UI

* Only save one account's maps in each cache item

isolated and therefore not reliable. This fixes the issue by clearing
the cache after each specs.

Some available languages lack translations for notification mails. Now it
tests for two languages which is certain to have required translations:
German and English.

German is the language the current project owner, Eugen Rochko speaks, and

* Save metadata from video attachments, put correct dimensions into OG tags

* Add twitter:player for videos

* Fix code style and test

Reasoning: HTML title tag affects everyone. But OpenGraph only affects
when somebody is deliberately sharing the content, usually in an
environment where such content is expected. Hiding the content in
OpenGraph tags results in deceitful previews which inhibit the
shareability of the post.

Example: Somebody writes a clever post about politics but kindly
puts a "uspol" content warning on it. Mastodon users are thankful,
but sharing this post on another platform results in non-Mastodon
users believing the entire contents of the post is "uspol" and not
clicking through/reading and re-sharing.

the slight mismatch in hashtag regex between js and ruby was causing

* Add option to show only local toots in timeline preview
Right know, toots from all the known fediverse are shown in the main
