basic implementation as String instead of Number

chatting with Yoric, it turned out JS Numbers can only store 32 bits numbers (hence ctypes.UInt64!). So here is another basic implementation which returns a String that can easily be parsed by ctypes, like this:

      let nativeHandle = baseWin.nativeHandle;
      let gdkw = new gdk.GdkWindow.ptr(ctypes.UInt64(nativeHandle));

Note this version returns the protected pointer to the actual native window (HWND, GdkWindow*, ...), instead of the actual address of the window as previously implemented.
