Persian (fa_IR) translation

Hi. This is the Persian translation. Please take a look. If you merged it in a way that I can check it online, please let me know so that I can test it and see if something is wrong, and also to see how can we fix the RTL problem.

I only worked with the web interface of github. I first made a wrong directory name, and I don't know how to delete it in the web interface. Please ignore the directory ' poche / locale / fa_IR.utf ' and just consider ' poche / locale / fa_IR.utf8 ' as the translation.

Cheers,
Masoud
