provision 6.x-1.1

The Aegir team is happy to release the second stable release in the 1.x branch. We have found two critical bugs during the more massive deployment of 1.0 and figured we could share the fixes with the community.

The major changes here are that 1.0 had broken the upgrade of Drupal 5 sites and was still allowing duplicate sites to be created under some circumstances.
