Return commit history from create_status_json

[mattmontgomery]

This is a work-in-progress PR to add commit history for data, results and sources repositories.

To support an output that includes git commit history, an environment variable with a Github token will need to be set.

Example: GITHUB_TOKEN=... django-admin.py create_status_json > ../openelections.github.io/data/state_status.json

Just out of curiosity (feel free to ignore....):

Is this associated with an "issue" in github, for more context?

To support an output that includes git commit history, an environment variable with a Github token will need to be set.

Who needs to set it, and when?
