v2.2.3: new maintenance/debug command and purge var deprecation.
Following the latest support ticket I helped to resolve, I just added a new maintenance/debug variable to force groovy scripts registration.
When adding documentation, I realized that the nexus purge procedure was not described and that it was using a var not following naming convention. This was fixed as well.
Since the purge var is now deprecated in favor of nexus_purge, I added a deprecation test and moved all existing deprecation tests to their own include file.
