Enhancement: Jenkins Integration

- Added configuration parameters to Tox's use of 'nosetests' so it generates the nosetests xml report
--- Py33 generates py33.nosetests.xml (per py33 environment in tox.ini)
--- Py34 generates py34.nosetests.xml (per py34 environment in tox.ini)
--- Other environments if introduced should genenerate nosetests.xml (per setup.cfg)
Enhancement Jenkins: coverage.xml

- Adds coverage.xml in the same manner as the nosetests.xml
Bug Fix:

- Added positional args to the nose runs
- Added the nose generated xml files to gitignore
Merge branch 'master' into enhancement_jenkins_testing
Cleanup

- Ops is adding the functionality via the command-line in Jenkins, no need to have it here since we don't care about it
Bug Fix

- Enforce that Unit Tests run in their own unique environment
--- Jenkins had a problem when it ran two environments simultaneously on the same box
- Re-ordered imports for affected files
