Consolidated Course Structure API Client

Corrected Cache Key Encoding Issues

This consolidations removes duplicated code and adds the ability for the access token to be overridden by Django settings. The override should make it easier to specify an access token if the authenticated user does not have one, specifically when running tests locally using a course structure API client on another machine.

Returning HTTP 200 if Course is Missing Submissions or Assignments

Replace zeros with hyphens in the performance pages.

The templates will adjust accordingly to inform the user of the problem.

New regex matches re-run/split-mongo block IDs (as well as existing block IDs).

- Using Unicode when formatting strings that might have Unicode values
- Properly encoding cache keys before hashing to MD5

Since the settings now have compressor enabled, the compress management command should be run at least once before tests are run; otherwise, an error will be raised.
