Upload all stable binaries to torproject debian repository
Currently only the latest stable version is included in torproject repo.
Example: https://deb.torproject.org/torproject.org/dists/jessie/main/binary-amd64/Packages has the latest 0.3.1.x series.
It would be helpful to be able to apt-pin system tor to a particular major version (ie 0.2.9.x) and receive security updates while testing compatibility with the next major version. At the moment, updates to 0.2.9.x must be built and distributed by a third-party even though 0.2.9.x is an LTS release.
