Currently categorization-support provides the interface CategorizationSupport but doesn't come with a default implementation. This would mean that if someone uses categorization-support without implementation, this would fail as Guice can't find an implementation for this component.

This becomes a problem when working with optional dependencies, i.e. STK to the categorization module. The null/default implementation in STK would override the proper implementation of the categorization module.

Tasks

1. Create proper module for categorization-support (rename it to magnolia-module-categorization-support)
2. Add default implementation of CategorizationSupport
3. Add module-descriptor with component definition to default implmentation
