Carbohydrates: packing fixes/improvements
This merge will correct a major issue with packing residues that are glycosylated -- namely, that should never have been happening to begin with.
This merge will also prevent packing of virtual atoms on carbohydrate residues, something that was a huge waste of time and memory.
All unit tests pass. carbohydrates and vancomycin unit test changes expected.
