------------------
- launchpad 1154719: freeze-to does not take the correct bzr revision number
- launchpad 1133248: "need more than 1 value to unpack" if some bzr's
branch.conf has extra content not in the key = value form
- support for bzr stacked branches for the server branch in the same
way as was already done in addons.
- launchpad 1152808: corrected parsing of options.log_handler in
gunicorn setups (introduced a constant to treat comma-separated list
options in gunicorn conf)
- launchpad 1153036: avoid pulls in case the specified revision is
a fixed one that we already have (bzr and hg only)
- launchpad 1115504: extract-downloads-to now works with bzr version
shipping with Debian squeeze
