* 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

* 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'

/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
