Merge pull request #723 from RosettaCommons/rhiju/remove_backtrace_in_pose_from_annotated_sequence
removing print_backtrace from disulfide backwards compatibility code …
only changes are in expected test (rs_loophash) and broken tests (hotspot_graft, place_simultaneously).
Some match tests are giving change in output order on mac.clang.integration (but not linux) -- this appears to date to my on_th_fly_residue_types merge, and I am looking into it separately.
