Patch to address this issue.  When combined with my NUTCH-738 patch will address the shutdown not releasing the classes and classloaders.

> NutchBeanConstructor is not cleaning up upon application shutdown (contextDestroyed()).   It leaves open the SegmentUpdater, and potentially other resources.  This causes the WebApp's classloader to not be able to GC'ed in Tomcat, which after repeated restarts will lead to a PermGen error.
