* Adjust status embeds

Adjust styles of embed code. Adjust styles of embed pages. Fix overflow of embed-modal.

* Remove trailing whitespace

* Using width from the variable

Some little changes to "ar" locale

- Fix assumption that `url` is always a string. Handle it if it's an
  array of strings, array of objects, object, or string, both for
  accounts and for objects
- `sharedInbox` is actually supposed to be under `endpoints`, handle
  both cases and adjust the serializer

* Show pinned statuses only in the top of the profile page

* Refactor AccountsController#show_pinned_statuses?

Overwrite values from rails-i18n by manually overwriting in every locale.
We want numbers like 1.5K in every language

* Update hr.json

* Update hr.json

* Update: some missing strings

* Updates missing strings

* New string

* Update oc.json

* Update oc.yml

* Update oc.json

The path template of the attached files must explicitly be defined because
it is contradicting to the name of the class.

* Make "unfollow" undo pending outgoing follow request too

* Add cancel button to web UI when awaiting follow request approval

* Make the hourglass button do the cancelling

* Raise an error for remote url in StatusFinder

Previous implementation had allowed remote url with status id which also exists on local.

Then that bug leads /api/web/embed to return wrong embed url.

* Fix oembed_controller_spec

* Fix NoMethodError in Web::PushSubscription

```
undefined method `site_contact_email' for #<Class:0x00005976d13c40>

/usr/local/bundle/gems/activerecord-5.1.3/lib/active_record/dynamic_matchers.rb:22:in `method_missing'
/usr/local/bundle/gems/attr_encrypted-3.0.3/lib/attr_encrypted.rb:295:in `method_missing'
/usr/local/bundle/gems/attr_encrypted-3.0.3/lib/attr_encrypted/adapters/active_record.rb:129:in `method_missing_with_attr_encrypted'
/mastodon/app/models/web/push_subscription.rb:53:in `push_payload'
```

* Specify serializer in Web::NotificationSerializer

* UploadArea should only preventDefault for Escape

This will make accessibility for some things less effortful, since we won't have to define a prior event handler to do whatever should be happening by default.

* Remove workaround for fixed bug in SettingToggle

SettingToggle was toggling itself in response to keydown of space, and then the keyup was doing it again

* views: Adjust heading positions

* Adjust settings pages

Adjust label. Adjust tables. Adjust admin/reports/* pages. Fix 2FA QR code style for narrow devices. Widen several pages. Increase contrast.

* Remove trailing whitespace

* Disable embed modal when private status

* Remove `reblogDisabled`

Using _: property names is discouraged, as in the future,
canonicalization may throw an error when encountering that instead
of discarding it silently like it does now.

We are defining some ActivityStreams properties which we expect
to land in ActivityStreams eventually, to ensure that future versions
of Mastodon will remain compatible with this even once that happens.
Those would be `locked`, `sensitive` and `Hashtag`

We are defining a custom context inline for some properties which we
do not expect to land in any other context. `atomUri`, `inReplyToAtomUri`
and `conversation` are part of the custom defined OStatus context.

* Add link to 'noscript' message
