- Allow tests to fail on Traivs.
 - Add new environment that just runs the unit tests that does not fail though.

 - Depend on galaxy-lib.
 - Move things into pulsar.util and/or pulsar.client.util as makes sense.
 - Use more Galaxy idioms.

- 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.

Don't attempt to install pyOpenSSL by default - it is problematic and I think it can prevent people from trying the LWR. Expand out the section about LWR security however with more information about install pyOpenSSL on Linux and on Windows. Also fill out a section on message queues. Other small readme improvements.

Add more automodule docstring annotations. Actual code documentation is somewhat pointless though since LWR doesn't have a ton of useful docstrings.

Mirrors change made by @dannon to Galaxy.

Looks like circus is not available for Python 3. Add some support for chaussette without circus for the Python 3 use case.

Break requirements file into main and development requirements. Move from tools/pip-requires to requirements.txt and dev-requirements.txt. Update README and travis configuration to reflect changes.

More aggressive job killing, kill children and grandchildren processes, by adding dependency on psutil (http://code.google.com/p/psutil/).

Light-weight runner is now a lot less light-weight. Implemented queueing (in addition to traditional running without queueing mode), multiple queues can be enabled, queues can be persisted with python shelve module (just need to set shelf_filename in server.ini), added note about persistence to server.ini.sample. Handle server shutdown properly now that we have queues in infinite loops. Rework check_complete to handle a 'queued' sort of state before the job has run.
