appview/pages: show co-authors and committers in commit messages
in smaller views of a commit, such as logs, only the profile pictures of
coauthors are shown, and the lead author's identity is suffixed with a
"+ N" to indicate co-authors.
in larger views of a commit, such as the commit view, the authors and
the committer are explicitly laid out, DIDs are resolved where possible
and shown alongside profile pictures.
