Fix Bug 560 and NEWT window closing behavior in general for all platforms.

- NEWT/WindowImpl:
  - 'void windowDestroyNotify()' -> 'boolean windowDestroyNotify(boolean force)', allowing to signal a forced close,
    as well as replying whether the window has been closed. (called by native code)

  - destroy(): set states before releasing the window lock

- NEWT/X11: Pass windowDeleteAtom for reconfigure window, in case of reparenting child to top-level

- NEWT/OSX:
  - Add 'BOOL windowShouldClose()' impl., ie. having a chance to reject the close attempt
  - Common impl. for 'windowShouldClose' and 'windowWillClose' -> 'windowClosingImpl'
    utilizing new 'windowDestroyNotify' code (see above).
    Fixes bug 560.

- NEWT/JOGLNewtApplet1Run: Refine out-of browser window behavior for window-close button
  - default: move NEWT window back to browser parent
  - closeable: close NEWT window

- jogl-test-applets: Add NApplet-Closeable test (Applet out-of browser window is closable)
