amazon 6.x-1.0-rc3

Mostly bug fixes, but 4 new features:

1. You can use an amazon.com|co.uk|de/etc link to an item in filters or CCK field instead of just the ASIN.
2. ISBN-13 is supported (It looks up the ASIN from Amazon)
3. Dashes are allowed now in ISBN numbers (or anywhere else)
4. Upgrading from the AmazonTools module (D5) is now supported. It's not perfect, but it's there. It requires some manual attention. See the handbook page that asb kindly put together.

If there are no problems with this release, it should become 6.x-1.0.

• #288577: 13 digit ISBNs / EAN support / converting to ASINs by rfay, tirsales, mleicester: Added 13 digit ISBNs / EAN support / converting to ASINs. With this patch, both EANs (ISBN-13) and Amazon.com/co.uk/de, etc. links can be used in either a CCK field or an Amazon filter. Also, hyphens are ignored in the input, so you can use a classically formatted ISBN-10 or ISBN-13.
