Bug 1222 - NEWT OSX: setAlwaysOnTop() and setAlwaysOnBottom() not working

- The NSWindow level must be set at window creation

- Levels are
  - aontop: kCGMaximumWindowLevel
  - aonbottom: kCGDesktopIconWindowLevel (w/ input)
  - normal: NSNormalWindowLevel

- Hence we need to recreate the NSWindow if toggling the state,
  similar to opaque .. etc.
