Title: Grib steps bug

A partial fix for a specific user's real problem (loading GRIB product template 4.9 probability data).
Also adds a warning attribute into cubes loaded with unsupported GRIB product templates -- **which still includes this one**.

This is logically 'prior' to outstanding work on -- https://github.com/SciTools/iris/pull/184 , which will hopefully streamline writing of GRIB tests in future.
