[FEATURE] webmention

It would be great to integrate webmention support with manual submission form.
That way blogs can be more easily connected and communicate with each other.

see this article: https://anaulin.org/blog/adding-webmentions/
it used this https://github.com/PlaidWeb/webmention.js for displaying the webmentions
