(Replaces #4541) Ensure that GALigandDock's sample_ring_conformers option is actually obeyed
This replaces pull request #4541. It ensures that the sample_ring_conformers option actually behaves as expected, and also adds an integration test for docking a single amino acid residue. The previous PR had been based atop changes that are now redundant (and which were part of a PR that has now been closed); this one is based off of master.
Thanks to Frank for the review!
