ERP5 Software Release: Pin all git repositories
( for 1.0 branch )
Since !258 (merged) we configured buildout to only accept pinned eggs. In fact, it's still accepting installing develop eggs and when this develop eggs have a new dependency we realize (too late) that software release was not repeatable.
After f5fc6d6d we use master branch of cloudooo, when cloudooo got a new dependency to pyPdf in cloudooo@0ff799eb installation started to fail.
This MR is just about pinning the git repositories to stop the build from failing, I have not actually tried if these revisions where OK.
