In naturalsort there is handling for Float, Decimal and Scientific notation. This looks for numbers like: '10.04f','10.039F','10.038d','1.528535047e5' It was breaking port sorting for ports named like "D1", "D10" etc. Have removed support for sorting these numbers as it's unlikely we need that in Netdisco, for now.
