Bug 1211: Refine NEWTDemoListener, JOGLNewtAppletBase

- NEWTDemoListener.createPointerIcons(..)
  - Use Display instance
  - Simplify PointerIcon creation using a list,
    skipping all non-found resources.

- JOGLNewtAppletBase
  - Bring back reparent action via key 'r'
  - Drop redundant PointerIcon, using NEWTDemoListener
