Amazon Shipping Filter by vallant

This plugin is based on the script provided by https://gir.st/blog/amazon-shipping.htm.

It will scan through all search results on the amazon page, see if it is shippable. if not, it will grey out the result for you.

Note that this is the first version. Because the shipping information is on another page which needs to be loaded in the background, it takes some time and might stress your CPU a litte.
Also, while testing i've encountered some Amazon counter-bot measures because of the many requests the add-on performs in the background. This means that if you shop extensively on Amazon, the detection might not work for a short while.
I hope this can be fixed in further versions.

Note that amazon may choose at any point to change the design of its site, effectively breaking the behaviour of this add-on. I'll try to keep it up-to-date, but can make no promises.
