Subject: Refactored demos to mostly subclass common Demo superclass providing
 shutdown capabilities. Moved DemoListener to demos.common package. Added
 ManipManager removal code to demos using manipulators or ExaminerViewer to
 fix memory leak when run in JRefract harness. Added workaround for another
 seeming memory leak when run under current JDK 1.6 due to java.awt.Component
 now being finalizable and keeping data alive longer than previously. Made
 ManipManager.unregisterWindow more lenient with respect to null or invalid
 arguments.
