Subject: Allow user-overriding of default email domain

Lazy projects where svn user X has email X@project.org don't need to
compile (and update) an identity-map for rolling conversions.

This can be mixed with a real identity-map, so only misses in the map
will have the user then show up as X@project.org

Also change the defaults somewhat. I don't like the NFS reserved
username nobody to show up in SVN or git logs, but am keeping that for
now.
