Debian packaging now available!

Henry Graham has provided some Debian packaging files, I’ve added his install notes to the packaging/debian directory on the integration branch.
Since this was named ‘debian’ as a directory before (I’m not a Debian guy), I suspect this may require some changes to his instructions. Ideally we’ll
just have a “make deb” target like we have with RPM (patches welcome).

We should probably also look into what it would take to get things into Debian/Ubuntu at the distribution level since we are also per suing this for Fedora/EPEL
right now. (Volunteers?)

Anyway, for those looking for packages on Debian/Ubuntu, this is for you, and please help test.

Thanks!
