Check best practices for the protein-peptide docking

[AnnaKravchenko]

Check which automatic changes haddock2.4 server does for protein-peptide docking and, if needed, update haddock3 protein-peptide tutorial.

Settings should be the same as what is defined in the protein-peptide example in haddock3 - check docking-protein-peptide-full.cfg

Mainly:

1. peptide defined as fully flexible
2. number of MD steps increased by a factor 4
3. dihedral restraints for secondary structure elements
