enhancement: support wishlists

[deutrino]

Thank you so much for building this wonderful project, I have been looking for a solution like Coindrop for quite a long time.

Recently when I set up a Coindrop to collect donations for surviving family of a friend who passed away, a couple people asked me if their Amazon wishlist could also go on the Coindrop page.

This wasn't the first time I'd thought of this (as I previously wanted to add my wishlist to my own Coindrop) but given the situation, once a couple more people asked me about it, I figured I would make a feature request.

Presumably wishlist URLs would have to be validated on a per-provider basis (e.g. Amazon, Walmart, etc), otherwise people could just paste in any arbitrary URL into any wishlist "payment method" which would open things up for abuse.

I will be adding, hopefully within the next few weeks, the ability to add any arbitrary payment link :)
