gtFillCrystFields : fixed name 'cryst.sg' for FABLE calculation of symmetry operators instead of 'cryst.opsym', which is filled already using the XOP/Diamond calculation
gtCrystCalculateSymmetryOperators : changed 'opsym' to 'sg' to be consistent with parameters.cryst; changed fields of 'sg' to 'rot' and 'trans' instead of 'sg_rot' and 'sg_trans'
build_list_v2 : updated the default list of parameters
