For inclusion with galaxy.

 - Restore it but in pulsar.util.
 - Fix #91 while at it.

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

 - Add pip installed script for submit.py (pulsar-submit).
 - Rename script for run.py to pulsar-run.

This should be a little more accessible an entry point for client side stuff then staging Galaxy jobs as an example.

Includes a generalizations for how dynamic outputs are collected from the working directory, this was going to be needed to implement discovered datasets on the Galaxy side anyway.

 - 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.

- 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.

Couldn't get pulsar on PyPI.

 - Add pulsar-config script that sets up a directory with server.ini
   file describing web process and app.yml describing Pulsar
   configuration..
 - Move run.sh into scripts and rename to just 'pulsar', modify behavior
   to target configuration files in current working directory or directory
   specified by -c/--config or PULSAR_CONFIG_DIR.
 - Add a new mode `--mode webless` to pulsar/run.sh that acts as an
   entry point into pulsar.main and starts pulsar without a webserver
   for MQ operation.
 - Move test/check.py into pulsar/clint/test/check.py so it is installed
   with pip. Add entry point so 'pulsar-check' is available after installing
   pulsar via pip/setup.py.

 - Add a version.
 - Add a HISTORY.rst file.
 - Outline a setup.py.
 - Update .gitignore for build artifacts.
