NEWT Lifecycle remodel: Window destroy() !

NEWT's removed:
   Window:         destoy(boolean unrecoverable)
   Display/Screen: get/set DestroyWhenUnused(boolean)

We behave as follows:
   - Window.destroy() always decr Screen's reference counter,
     which issues destruction when reached zero.
     Then Screen does the same for Display ..

   - Window.destroy() keeps alive all references,
     hence it can be always recreated via setVisible(true).

   - Window.destroy() ensures Display's EDT is stopped
     if display is destroyed.

   - Window.invalidate() actually removes all Object reference,
     hence it cannot be recreated or used after it.
     This method exist to support a way to cleanup memory, GC.

All test passed on Linux/X11 and Windows
