Bug 934, Bug 935: NEWT: Add support for custom Application/Window and Pointer Icons

- Utilizing JOGL's PNG decoder for all icons, if available.

- Application/window icons:
  - Providing default application/window icons in 16x16 and 32x32 size
  - NewtFactory.setWindowIcons(..) or property 'newt.window.icons' maybe used to override default icons.
  - Using icons at application/window instantiation

- Display.PointerIcons:
  - NativeWindow Win32 WindowClass no more references a default cursor
    in favor of fine grained cursor control [in NEWT]

  - Display provides create/destroy methods,
    where display destruction also releases open PointerIcon references.

  - Window.setPointerIcon(..) sets custom PointerIcon

- Implemented Platforms
  - X11
  - Windows
  - OSX

- Manual Test: TestGearsES2NEWT (Press 'c')
