0.21.1.1004 RC

- Intro: Server connection check. If app is unable to establish connection, it will suggest you to add proxy or ask for help.
- Intro: "Continue in English" button
- Intro: "Start Messaging" button transparently loads & applies cloud localization
- Intro: Asynchronously applies recommended language, when needed & shows "Continue in English" with animation
- Screens, for which it's critical, are now always translated, without depending on the internet connection.
- Improved: Sign out pop-up
- Fixed: inline bot placeholder position when font scaling is enabled

Translations support is finally complete. To summarize:
- Future translations will not require an application update
- New translations will not affect APK size at all
- For available translations only couple strings are integrated into the application for smooth experience, which adds almost zero KB to the APK size
- Install localizations from files
- Create your own localizations without leaving the app
- Plenty of useful tools for translators

For testers: please sign out & clear application data to test first launch & sign-in chain.
If no critical bugs will be found, this version will go to production.
