[typo corrected at ProteinResidueConformationFeatures]
[update of SandwichFeatures]
- change from 'fn3' to 'fnIII' because 'fnIII' seems more correct
according to '2008_Manipulating the stability of fibronectin type III domains by protein engineering'
- should not change any integration tests other than (expected) features and features_database_schema (if any)
