0.10.0

Originally written on lamb-releases: This release brings your blog into the IndieWeb conversation — webmentions, reply posts, and WebSub — and makes Lamb much easier to install and upgrade. Added Webmentions: your blog now sends webmentions to sites you link to when you publish (including reply-to targets), and can receive webmentions from other sites. Received mention authors are shown on the post for the author when logged in. Reply posts: link to a post you're replying to and Lamb shows the reply context above your post.
