RTL language support (Persian/Farsi)

[bambier]

Add support for RTL languages such as Persian

First we cant use set font for widow title as we cant set font for that
Second we can fix Text with arabic-reshaper and python-bidi but its not good practice its better to use pango for implementation of Text

PS: using arabic-reshaper and python-bidi wont fix InputField

Sample Persian (RTL) text: زن زندگی آزادی
