Adding option to weight protein-ligand interactions in coupled_moves protocol
The weight of residue-ligand interactions can now be specified using the flag coupled_moves::ligand_weight (Real). The weight is 1 by default, meaning that residue-residue and residue-ligand interactions are scored equally. Setting ligand_weight to 2 up-weights the residue-ligand interaction energies by a factor of 2.
This branch also contains two other changes, including changing the access specifier of set_last_accepted_pose and set_lowest_score_pose in MonteCarlo to public and adding compute_one_and_two_body_energies to RotamerSet. These changes were needed to incorporate ligand weighting into BoltzmannRotamerMover and the coupled_moves protocol.
