Updated module versions to 2.4.0.Beta1 for release
Removed Kitchen Sink archetype from quickstart guide (external BOM makes it too difficult for users to adapt to their own needs)

Added required Maven metadata to the new module poms that lacked it
Back to 2.4.0-SNAPSHOT
Allow any class that implments IsWidget to be annotated with @Page
