Updated README-REPO to reflect restructuring of directories. See https://answers.launchpad.net/duplicity/+question/252898
Corrected the extra dot in the stable branch line at step 1.
Change the branch for stable. lp:duplicity/stable doesn't exist and so I've changed this to lp:~duplicity-team/duplicity/0.6-releases as this is the only non-Windows, non-dev branch.
* Merged in lp:~hooloovoo/duplicity/updated-README-REPO
