hgweb: show users recorded in obsolescence markers

It's useful to see who obsoleted a commit, because it's not always done by its
author (hg-committed is a good example, because people rebase stacks of commits
made by various people).

Usernames are obfuscated, but look correct (e.g. "test" is
"test").
