Defaulting to zero to avoid downstream issues with None values.

Education level returned as a string.

Added Enrollment Mode

Updated enrollment/gender endpoint to aggregate gender counts by day.

Added REST API for Grade Distribution and Sequential Open Distribution

Updated Course ID Regex and CSV filename

File names are now compatible with opaque keys.

This regex is nearly identical to the one used by LMS. The only difference is the internal capture groups have been replaced with character sets to avoid issues with the Swagger UI attempting to parse the internal capture groups and pass them along as arguments.

Updates for Travis

- Added new make target
- Updated fake data management command to accept an argument determining the amount of data to generate

Removed forum data from activity resource

We don't currently have the data. I have commented out the relevant code.

Remove deprecated setting; replace with new version.

TE-476

Redirecting Status sub-paths to Root

Calls to /api/v0/status|health|authenticated are now redirected to /status|health|authenticated.

Grouping Unknown Locations More Efficiently

Grouping and Returning Unknown Locations

Enrollment-location rows without a valid ISO-3166 country code are grouped into an UNKNOWN entry returned by the API.

- Start dates are on Mondays
