CubicWeb 3.0.1 bugfix release

Shortly after the release of CubicWeb under the GPL licence, we've release a quickfix version to correct a few bugs :

• XHTML validity wasn't always there because of a bug in cutting parts of texts
• cubicweb-ctl had a few things corrected
• permissions on certain actions we're properly placed
• a few bugfix in the generation of the configuration

The new version is 3.0.1, you can see the corrected tickets here.
