Try to detect removal of *.deb files in update_repository()
Test coverage is no longer at 96% :-( (it's more like 92%)
Bug fix: Respect build_package(copy_files=False) option
Make Python >= 2.6 dependency explicit in stdeb.cfg (part 2 :-)

See 1c3b824b997e4d90212e11d7dd80c938d1519573 for part 1 (where
I edited a generated file...)
Test GPG key generation (awkward but useful, make it opt-in or opt-out?)
Documentation bug fix: Update usage message & README
Make repository generation user configurable (~/.deb-pkg-tools/repos.ini)
Support for system wide configuration file (/etc/deb-pkg-tools/repos.ini)
