Xiaomi Geeks Bot (@XiaomiGeeksBot) V2 is here!

The bot has been re-written from scratch with tons of improvements and cleanups, you'll note the dramatic increase of responding speed!

I have kept everything in commands as you've used to, with some touches here and there.

This update of the bot introduces some new feature that gives you the best of @XiaomiFirmwareUpdater, @MIUIUpdatesTracker, and @MIUIVendorUpdater.

- Now you can subscribe to your device updates of firmware, MIUI, or vendor so easily using subscribe command. Read subscriptions help section for more details.
- Are you using the bot in a device specific group? With this update you can set the preferred device of a chat with /set_codename codename in order to be used as default for commands that needs the codename of the device.
- Multi-languages are here! Thanks to the awesome community, bot has been translated into Arabic, Chinese Simplified, French, German, Italian, Polish, Portuguese (Brazilian), Spanish, and Turkish! You can change the language using /set_lang command in your pm, and your group if you're an admin.
- Bot help has been more simplified into groups, and I've added usage example of every single command.
- You can manage your bot options using /settings command.

Note: You can contribute to bot translation on crowdin if you'd like to use the bot in your own language.

I'll wait your feedback and bugs reports :D
