I've cleaned up the readme file.

::: New in this version! :::::::::::::::::::::::::::

1. If you have a product that has a price of 0.00 and want to hide that price and display a predefined text instead this is now possible.

2. Changed is that in the product listing the Buy Now button is replaced by a button that when clicked, it will take you to the product details instead of showing the no-active Sold Out Button. This is much more friendly for you customer.
