Merge pull request #436 from RosettaCommons/smoe/nick/antibody_py_revival
Antibody.py missbehaves - GraftedStemOptimizer.cc
Fixes antibody_graft, turns antibody_graft integration test back on.
Expected integration test failure:
antibody_graft - should only fail on this commit during reinitialization; should be stable afterward.
Other test failures from benchmark revision 1433 existed at time of pull request creation, have been fixed in master since.
