Comment 3 for bug 121709

Changes in debian/rules: This is target 'clean'. It is also invoked when source package is built.

1. As file debian/copyright file is generated from upstream source and files in debian/copyright-files it is actually redundant. To make reviewers' life easier we kept it in source package ie. rm of debian/copyright was commented out in debian/rules. Reviewers need not build binary package to see complete copyright file. I reversed this change. Disadvantage is that to get correct up to date version of debian/copyright one has to first build binary package to get regenerated file debian/copyright.

2. List files (second change in debian/rules) are auxiliary files. They are not necessary and should not be present in source package. I also added note to changelog.

Summary:
1. I reversed deletion of debian/copyright.
2. debian/copyright is now part of source package
3. changelog is updated - -rm -rf $(d_lists) is now performed in clean target.
