Add support for pashto and dari languages

[MirwaisAkrami]

As the Jalali calendar is used in Afghanistan as well, this library fits our needs perfectly here, except for the the names of the months, which needs to be translated to Dari and Pashto

Just as the support of Farsi is added, if you could add support for Dari (fa-AF) and Pashto (ps) as well.

I have checked the library code and I think the only modification we will need is to make the locale to be chosen from three languages rather then just 'fa' and add moment.updateLocale('fa-AF', {}) and moment.updateLocale('ps', {}) for the two languages.

I can provide the locale objects for both the languages if you agree to add them and will provide any further technical assistance if required.

Yes I think so, there shouldn't be any problem
Try the idea and let us know in this issue
then we will merge it or add a link to the fork that you have created.

[MirwaisAkrami]

Sure, I will implement the feature and will let you know.
