Docking scripts

• irmsd.py : applies to atomic models by default -> this should be changed to default=coarse-grained
  does not superpose the interfaces by default -> idem, switch the default to the contrary
• fnat.py : only applies to coarse-grained models; needs an option for atomic representation
• fIR.py : idem (plus, its name has been changed from fpib.py to fIR.py -> change the name in all scripts
  that import fpib)
• add a script rmsd.py
• energy-mapping script : replace by Charles' version
