Versioning policy

As Geotoolkit project is now mosty a sandbox project, we’ve decided to move away from semantic versioning. The new versioning scheme is a calendar based versioning of the form YY.MM.dd[-patch-number].

Warning

No retro-compatibility policy is enforced anymore on the project. It means that a breaking API change can occur without any previous notice between two tags of the project.
