Move all modules to a single release cycle

Move to a unified release process whereby all we tag all modules together:

This will enable users to checkout from the tag and build directly. The drawback is we'll no longer have assurance that we lock individual modules inbetween releases.

• Inherit version from build parent
• Use ${project.version} for intermodule dependencies
