Webmention support

[davidcelis]

Looking through Indiekit's docs and a few old issues, it looks like Webmention has been on this project's radar for a few years but isn't supported yet. I thought it would be a good idea to open an issue and have a place to track development of Webmention support (both receiving and sending) if that's still planned!

@davidcelis Definitely plan to add support for Webmention; currently have it slated in for v2.0 (basically once Micropub is nearer completion), but some parts may come earlier. I’ve added a few tasks to your issue, though I may end up splitting this into separate issues closer to implementation. Thanks for your interest in Indiekit!

Native webmention support remains something I want to look at for v2.0. However, perhaps in the meantime an interface for webmention.io might be a good way to plug the gap? #740
