Merge pull request #292 from RosettaCommons/justinrporter/env_devel
Multiple small bug fixes to the broker (see commits 9854a39, 13d49bd, and 09033a4). No broken integration tests outside the usual failures or unit tests outside of the Windows pyrosetta build, which seems to be broken for everybody at the moment (and it wouldn't really make sense for what I've done to break it...).
