Enabling service for creating new 3rd party app services

Before creating a 3rd party app service, a Nursery service ApplicationServiceArticleEventListener needs to be enabled. This Nursery service creates a dedicated section for new 3rd party app services. Without this section, the 3rd party content fetching will not work. To enable this service, set the following in /com/escenic/community/thirdparty/ApplicationServiceArticleEventListener.properties:

enabled=true

This service should only be enabled on one ECE instance in a multi-server environment.
