------------------
- launchpad 1192973: 'clean' option now based on bzr clean-tree (more
powerful, and avoids in particular removing empty dirs, which is a local
modification that prevents later on freezing)

------------------
- launchpad 1189402: order of the addons_path is now deterministic
- launchpad 1189162: registry helping avoid double evaluaton of
custom addons models (helps launching unittest2 tests directly)
- launchpad 1191279: first implementation of new 'clean' option,
dealing with python object files only.

------------------
- launchpad 1188402: fixed git clone init on a precise revision

------------------
- launchpad 1183005: python interpreter that can bootstrap OpenERP
and open a database for interactive session or to launch a script.
- launchpad 1182589: avoid IOError if a bzr branch has no branch.conf
- launchpad 1185097, 1185100, 1185101, 1185741: advanced support
for Git (precise revision, freeze, extract) allows including Git
repositories in a full release process for tarball deployments.

------------------
- launchpad 1182146: clearer user feedback and exit status code = 17
for freeze-to in case of local modifications of VCS server or addons.

------------------
- launchpad 1169124: regression: offline mode not honoured with bzr
