------------------
* Upgrade step: Within "Plone > Site setup > Add-ons" click on
upgrade button available for eea.facetednavigation
* Cleanup: Removed default object_provides widget for new Faceted Navigable items
[avoinea]
* Change: Removed default hardcoded sorting by effective date, reversed as
this can be easily accomplished with a sorting widget. Also added an upgrade
step that adds a hidden sorting widget by effective date
(if no sorting already present) in order to keep backward compatibility.
