Exporter
- Either active objects with a proper element name or all active objects are
  exported depending on EnumProperty in File dialog: all <-> element 
- Removed a bug in the exporter: 'import_pdb.ATOM_PDB_ELEMENTS_DEFAULT' is
  used instead of 'import_pdb.ATOM_PDB_ELEMENTS' <= is sometimes empty list

Importer
- The name of the representive ball of a dupliverts technique is now shorter:
  from 'Ball (NURBS)_<element>' to  'Ball_<element>'; The name of the element 
  is not cut in the outliner.
