 * An ApplicationContextAware ContextLoaderListener that allows for using the current ApplicationContext,
 * as determined by ApplicationContextAware, as the parent for the Root WebApplicationContext.
 * 
 * Also provides for specifying the contextConfigLocation of the Root WebApplicationContext, because
 * Eclipse Jetty 7 ServletContextHandler does not expose a setInitParameters method.
