Google Checkout: Added Shipping support to Google Checkout. Currently supports flat-rate-shipping, merchant-calculated-shipping and pickup, doesn't support carrier-calculated-shipping yet. I also updated the google checkout documentation to reflect the change, and added some tests. Added my name to CONTRIBUTORS.txt while I was at it
Google Checkout: Added ability to capture the private data on an item when they send it back
updated the docs a little
Added some missing fields to the AmazonFPSResponse taken from http://docs.aws.amazon.com/AmazonFPS/latest/FPSAPIReference/AWSFPSIPNDetails.html. All new fields have been added as null and blank true, so they won't break any existing Apps. I didn't see any way to do migrations (i.e. South) so I'm not sure what the proceedure is for this. Another idea is to add a new Model and then link to them one to one, but that is a little more complicated.
