Adding Arabic configurations

I have added some arabic configurations like :
Flags templates, date and time parser, many mappings, and others.
I hope someone will review these changes and spot errors if they exist.
Adding Arabic configurations

I have rearranged the Arabic configurations into the right alphabetical order.
Adding Comments and some missing codes

I have checked the missing codes, and added some comments above the Arabic configurations concerning the rendering of Arabic from right-to-left.
Cloned the project again and remade all the changes, I will see if this is gonna work well.
