Subject: NEWT: Add WindowListener.windowDestroyed() ; Remove
 WindowImpl.windowDestroyed()

Add WindowListener.windowDestroyed()
  To expose a proper window lifecycle, ie destroy-notify and destroyed,
  this notification is added.
  This will be used at least in unit tests, where we verify destruction.

Remove WindowImpl.windowDestroyed():
  This native hook (planned to be called by native destroy notification)
  is unreliable or not supported for all platforms.
  NEWT relies on the pre destroy native hooks and handles the final
  destroy notification itself.
