NEWT/OSX MacWindow.close(): More conservative closing approach.

Closing:
- Java: Set handle to null
- Native:
  - Don't release the NSView explicit, but rely on NSWindow's release

  - Don't use NSWindow close() but simply call release() instead.
    The latter doesn't produce a crash SIGSEGV on exit in some cases.
    OSX 10.7.2, NV GPU
