/**
* This is an enhanced equals for portlets that allows equality for unpersisted portlets. At times (like addPortlet)
* a portlet may have been associated with its window prior to being persisted. In this case we can consider
* it equal if it is associated with the same dashboard(1) and has the same positioning. Note that key-name pairing
* can not be used for equality as a dashboard is allowed to have the same portlet multiple times, with a default
* name. But they can not hold the same position.
* <pre>
* (1) Even the dashboard comparison has been made flexible. To allow for lazy persist of the dashboard (to
* allow for the default group or resource dashboard to not be persisted) we allow the dash comparison
* to be done by name if an entity id is 0. This should be safe as dashboard names are set prior to
* persist, and should be unique for the session user.
*
* @param storedPortlet
* @param updatedPortlet
* @return
