Price Difference Formatter

This module adds a new field formatter to show at the same time:

• The original price of the variation.
• The price with the promotions applied.
• The difference in price in percentage.

The initial idea arose in a project in which it was necessary to show the percentage of discount both in the lists of products and in the pages of detail.
