Release v0.1.1

Version 0.1.1 contains new features and small bug fixes. We have also begun work on the Python API; this API is presumed unstable and not yet intended for broad use.

New features:

• dsub supports combining command-line (--label, --env, --input, --output) and --tasks file flags.
• Label values are less restrictive (for example, they can now be numeric).
• Added new GCE zones (europe-west3, southamerica-east1)
• start-time is now included in dstat full output
• status-message is now included in dstat full output.
• --version flag was added to dsub, dstat, and ddel.
• local provider now supports relative paths to local input/output files.

Minor changes:

• run_tests.sh now displays test timing information.
• local provider container names are more user-friendly.

Bugs fixed:

• local provider job/task names are now validated to conform with docker container name restrictions.
• dstat date field formats are now consistent.
• Various local provider internal fixes.
