Title: Lps 45608

The original issue happened because activities portlet and members activities portlet use same friendly mapper url, when user click RSS icon in members activites portlet, portal throw Princinple exception because following code:
checkResource(ownerLayoutRequest, portlet); (line 164 SecurityPortletContainerWrapper)

Portal pass a wrong portlet (activities) to checkResource method cause throw Princinple exception, the portlet should be members activities portlet

To fix this issue, I followed the same idea of wiki to use pure struts to process rss request (refer to strutsExecute method of com.liferay.portal.struts.RSSAction, /html/portlet/wiki/node_action.jsp)
