Subject: * cmdline/apt-changelog: Read server name from configuration  
 APT::Changelog::Server instead of hardcoding it. This allows local users   to
 point to a local changelog mirror, or make this script work for Debian. * Add
 debian/apt.conf.changelog: Configuration for apt-changelog with the   server
 for Ubuntu (changelogs.ubuntu.com). Install it in debian/rules. *
 doc/apt-changelog.1.xml: Document the new option.
