* Add a (failing) test where the old system is used for quantities
* Use a cached Python Script to keep the universal quantity definitions:
  * erp5_content_long
  * delete the cache when a global quantity definition is changed via an
    interaction workflow on Definitions
  * Use the catalog to retrieve the global definitions
  * If no Quantity Definitions are defined _at all_, then it falls
    back and uses the properties on categories
