Wallet support & documentation

It would be nice to have a running track of which wallets work for the site. I'll use this issue to keep a running tab as I work on trying different wallets.

This info could go in some docs on the site or on github or just in a markdown. This will help if we try to get real people to use it too.

Also we could note any peculiarities we find with a wallet, perhaps they implemented a certain spec in a different way than others?

Review the existing site, GitHub documentation, and Markdown files to find where wallet compatibility information could live. Test the wallets identified in the issue, record which work and any implementation peculiarities or specification differences, and consider the work done when the results are captured in a maintained running list.
