libgdx MD2Loader modification to fix animation name truncation

MD2Loader.java

// in loadFrame()

int len = 0;
for (int i = 0; i < charBuffer.length; i++) {
  // The following line changes to do proper truncation of frame index
  // appended to the Marker name by the junaio export script from
  // http://www.junaio.com/develop/docs/documenation/general/3dmodels/
	if (charBuffer[i] == 0 || Character.isDigit(charBuffer[i])) {
		len = i;  // was len = i - 1 (off by 1 error)
		break;
	}
}

frame.name = new String(charBuffer, 0, len);
