  Adding the _atom_site_type_symbol data item to prevent confusion
  between hydrogen and holmium.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w=1/\s^2^(F~o~)' was changed to
'calc'. New tag '_refine_ls_weighting_details' was created. The value
of the new tag was set to 'w=1/\s^2^(F~o~)'.
