Release facilities to ease the management of buildout based projects.

This distribution intends to be as small as possible by integrating a few custom release choices done by the der Freitag development team.

For that it heavily relies on a couple of well known distributions:

• plone.releaser
• zest.releaser

A few zest.releaser plugins that:

• check that the git repository is updated update_git_branch
• update development branches after a release update_develop_branches
• check translation files are updated check_translations

Additions to plone.releaser:

• ability to release a distribution within the parent (buildout) project
  • check to ensure the correct branch on the parent project is used check_zope_branch
  • check that the distribution about to release exists check_folders
  • update versions.cfg with the new released version update_versions_cfg
• gather the changes on distributions (more than only collect_changelog)
• push cfg files publish_cfg_files
• check which distributions need a release
• update batou version pins (components/plone/versions/versions.cfg
