Bug 1421: NEWT OSX Invisible: Implement 'Fake invisible child window'

'Fake invisible child window' is implemented by simply moving the window out of sight (viewport).

- orderOut0 needs to use '[mWin orderWindow: NSWindowBelow relativeTo:..' parentWindow
  instead of '[mWin orderBack:..', otherwise the whole parent application gets invisible w/ SWT ;-)

- NewtNSWindow may also needs to use parent's Screen instance if moved offscreen,
  as the own Screen is invalid (zero size) in this case.

- WindowDriver: Adding special treatment for 'Fake invisible child window' (tagged as such):
-- reconfigureWindowImpl: setWindowClientTopLeftPointAndSize0(..) will be called
   using the viewport's max position -> out of sight.
-- screenPositionChanged: ignore the 'new' position
-- sizeChanged: ignore the 'new' size

This sensitive NEWT change set shall benefit other toolkits being used as parentWindow
besides SWT, as this behavior is the same across MacOS.
