SLING-3641 : added a wrapper 'JcrPropertiesSection', which wraps the 'JcrPropertiesView' into the standard Properties view. Hence we now have two ways of showing the properties: in the standard Properties view - or in the standalone JcrPropertiesView. We can still decide if we want to remove the standalone one at a later stage.
