Summary:
   allow for deletion of portlet settings during WAR update
 
Problem Description:
   During update of an portlet application WAR file certain portlet and application settings ar not deleted from portal datastore, since it cannot be destinguished between a user added property (that should be preserved) or a setting that was formaly provided (by the WAR developer) via portlet.xml. Therefore nothing was deleted during the update process and old or former parameters remained. The user/admin had to delete them manually via e.g. the Admin UI after the WAR update finished.
 
Problem Solution:
   The update.portlet.preserves.config.settings property defined in DeploymentService.properties was extended to accept additional values.
      
   The property can now be used with the following values:
     	update.portlet.preserves.config.settings = protect  or true          to protect existing values from being overwritten or deleted
      	update.portlet.preserves.config.settings = overwrite  or false    to protect existing values from being deleted, but allow to overwrite them with the new values from portlet.xml
      	update.portlet.preserves.config.settings = clean                         to clean existing settings, delete them and only recreate those found in the new portlet.xml
      
   Besides allowing the deletion of settings prior to update the APAR fixes another problem is fixed, where the anonymous-session property from ibm-portal-portlet-ext.xmi was not updated.
   The update.portlet.preserves.config.settings property defined in DeploymentService.properties was extended to accept additional values.
