Add Arabic language

Hi!

I'm looking to add the Arabic translation to the App.

Thanks @abdelhaqelamraoui! That would be an awesome thing to do. But let me look into this a little bit, because I think in general this requires adding support for right-to-left rendering of both strings and UI elements... I have not worked with those before and I'm not sure of the amount of work involved. Let me look into it and get back to you!
