Added _atom_site_type_symbol and _atom_site_occupancy to
the atoms loop to complete the structure as from the reference

Luca Lutterotti

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w = 1/\s^2^(F)' 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)'.
