New module: Product integration with eBay

This module allows you to combine all of your online store products directly with eBay.

From the product's reccord, on the content manager, it is possible to select the products that will automatically be integrated with eBay. Besides this field, it will also be manageable to create addicional fields for the final price and bidding (if aplicable), as well as the bid's duration.

Notes:
    - An external motor will be responsible for keeping data constantly in sinc with eBay.
    - This module will only help you with the automatic product integration with the auction website. In order to integrate resulting orders and transportation other modules will be needed.
