Version 1.5: Fix calls.

- Support for custom languages. Crowdsource a cloud-based
language pack for Telegram in any language using our
Translations platform - then apply it in real time.
- Interface scaling for large screens, up to 300%
(up to 150% for macOS retina screens).
- 'Count unread messages' setting for the Badge counter
in Settings > Notifications. Disable to show number of unread chats.
- Video messages displayed in shared media (under voice messages).
- Updated emoji. Farewell to question marks!

Also in this update:
- Listen to voice and video messages in 2X mode if you're in a hurry.
- Add a comment when sharing posts from channels.
- View all photos and videos in Twitter and Instagram link previews.
- Add emoji to media captions.
