Enable randomisation comparisons to apply to all lists generated by the calculations

[GoogleCodeExporter]

The comparisons between two spatial or cluster outputs, as used to generate
the randomisation results, are currently applied only to the indices in the
SPATIAL_RESULTS list.  

It would be useful to also apply this to other lists so one can asess, for
example, where the endemism weights in ENDC_WTLIST plot against the
randomly generated distributions.

An opt-out parameter needs to be added to the metadata to enable the system
to ignore some lists, for example ENDC_RANGELIST and ENDW_RANGELIST for
which the values are invariant.
