IAM bugfix and add job_tag option to ProtocolSettingsMetric
This PR has a few minor fixes and changes:
- Fixes IAM for a test case that @aleaverfay had. It also adds this test case as an integration test.
- Fixes scoretype setting in `PerResidueEnergyMetric` and adds the option to `TotalEnergyMetric` (which may now need to be renamed) @teetsf Both are now tested in integration tests.
- Adds a better description of custom_type option and updates RMSDMetric docs. @roccomoretti
- Adds an option, `job_tag` that basically passes a string to the score file. This is really useful for rosetta_scripts_JD3 to tag the job name in the scorefile to make it easier to concat and analyze.
