Added file, directory and overwrite force arguments to the structure.create_rotor_pdb user function.

Created the front end for the new structure.create_rotor_pdb user function.

This will be used to create a PDB representation of a rotor motional model.

Fix for a strange and extremely rare typo bug in the model-free specific analysis code.

This was identified by Manish Chaubey <manish dott chaubey att tuebingen dott mpg dott de> in the
message at http://thread.gmane.org/gmane.science.nmr.relax.user/1422.

This only occurs if a relaxation data error of zero is encountered and is a bug in the RelaxError
message explaining the problem with the data.
