New Testing PPA

Written for Déjà Dup by Michael Terry on 2009-06-04

I've created a testing PPA for pre-releases: https://launchpad.net/~deja-dup-team/+archive/testing

Right now, it contains a prerelease of the upcoming 10.0 release. A notable, testing-needed new feature is the use of GIO. Feedback appreciated (https://bugs.launchpad.net/deja-dup/+filebug)!
