renamed "contextProperties" attribute to "contextParameters" (matching web.xml naming); "contextParameters" contains Servlet/PortletConfig parameters as well; added default "servletContext" and "servletConfig" environment beans; added default "portletContext" and "portletConfig" environment beans; added default web scope "application", wrapping a ServletContext/PortletContext; MockPortletSession supports destruction of session attributes on invalidation
