backport 1.32

Yet another relatively minor update.

What with all the other stuff that's been going on in my life in the past year, I never updated my backport script to support backports to jessie or to reflect the new stable release. This release does that, at some email prompting (thank you!).

It also adds a new -A or --architecture flag to specify which build architecture to pass to pdebuild. I have no idea if this works, but it at least should in theory.

You can get the latest version of my backport script from my scripts page.
