------------------
* Upgrade step: run SITE/updateCreationDate
[ichim-david refs 21326]
* Feature: added updateCreationDate BrowserView which will set the CreationDate
to that of the EffectiveDate if the CreationDate is smaller than the
EffectiveDate
[ichim-david refs 21326]
* Change: order of versions no longer takes into consideration that
effective_date needs to be older than the creation date, opting to sort
by effective_date if that is found on the object.
This reverts the logic change done in ticket 20827
[ichim-david refs 21326]
* Bug fix: user must be able to create a new version with Add Portal
Content permission. Semantically creating new versions means adding new
content to the site. This way users can create new versions of published
content which it may be not editable anymore.
