ADL: Unbound model cannot be specified in the paramter library file

The files in the tutorial are very old and are not compatible with the
current autodock version. The keyword that is causing trouble is
"FE_unbound_model extended" in file "AD4_parameters.dat". You may find the
manual for autodock 4.2.6 more useful:
