Added support for iLO4 storage information.

I've added a patch that adds support for storage information from new iLO4 interfaces, as they are very different from the previous iLO2 and iLO3.

They currently live side by side as two different methods, but it could perhaps be an idea to create a wrapper method that selects the appropriate sub-method based on iLO version. Futureware for now.

This patch also requires the patch from poulhs to resolve some XML::Simple quirks.
