Add scraper for afghankitchenrecipes.com

[jayaddison]

This scraper would benefit from an implementation of #301 - the example recipe includes instructions and ingredients that relate to separate components of the resulting meal.

@jayaddison How many files have you changed and add for adding new website. could you please provide a summary and is it working fine?

[jayaddison]

Hi @gaurav19063 - usually there are four files that we need to modify for each website:

• [add] Python scraper code for the website
• [add] A test HTML file
• [add] A Python unit test that reads the HTML file and runs the scraper -- this helps to check that the scraper is working correctly
• [modify] The main recipe-scrapers Python module to add the scraper

Your comment made me realize that I'd accidentally added two HTML files here. Thanks!

@gaurav19063 Also, one more detail: there is a utility script called generate.py that can do a lot of the work of adding the new files and updating the main module for us.
