Adds a small button to unsubscribe from the useless and pesky emails that amazon seperates into 10 1/2 million different categories to make you give up on unsubscribing from all of them. Get it done in a single button press.

Just go here:
https://amazon.com/preferences/subscriptions/your-subscriptions/current-subscriptions

Especially useful if your bot signs you up for these sorts of things.
