Will help ensure these jobs eventually become terminal.

Start process of describing PyPI based installs and newer scripts such
as pulsar-config and pulsar-check.

 - Fix bug where jobs may have been recovered before the MQ callback was set on the manager.
 - Add a new LOST job state for jobs that cannot be recovered and the Pulsar is going to abandon.
 - Fire off callback for LOST jobs.
 - Add test case to verify callback is called for LOST jobs.

By default pulsar will use 0777 with current umask filtered out.

Closes #65.

It is disappointing it has been so broken for so long, but at least with this fix it sounds like it is working for @dctrud.

Fixes #63.

Should hopefully address the crazy issue #59.

Probably not needed - only hit the error condition because of other bugs - but I guess it is not hurting anything.

Forces a full setup step without having to actually create a non-empty setup_params dictionary. Galaxy would always pass a tool id and stuff in setup_params - but these should be optional.

Want to reuse it in a test.

Useful for debugging deadlock situtations.

(In case I need it in the future again.)

Eliminates required dependency on paste for Python 3 (though still need to update actual code for Python 3).

 - In setup.py don't depend on paste if Python 3.
 - All development dependencies are now compatible with Python 2 and Python 3, remove dev-requirements3.txt.

Various syntax problems since the last time I worked on Python 3 support.

This does indicate a problem with the tool shed install translation to the remote server though.

Docs build fine with 1.3 - but there is a new warning which causes linting them to fail and 1.2 is what is used by readthedocs.org as far as I can tell.

If there is some problem that causes the Pulsar client in the job handler to stop logging, this really should be logged now.

 - Add a join timeout incase this is is where things are hanging.
 - Don't allow heartbeat or sleep exceptions to halt queue consumption - shutdown events need to fire to actually stop this computation.
 - Add more logging to determine if this is a problematic spot.

 - Don't ack requeued messages (missing return seems like it was a bug).
 - More logging around this event.

Both still largely WIP.

- Just add PyYaml as required dependency - doesn't seem problematic
under Windows.
- Update setup.py to conditionally install nix bash script or Windows
bat script depending on platform.
- Outline some work on bootstrapping Pulsar install via PyPI (should be
merged into scripts/config.py at some point).
- Version update to PyPI publication tests.

Go further than runtime and ensure threads join so that they cannot interfer with other tests.
