- add a check for the feature flag before trying to save user info to the service

- on first visit to courseware, go straight to first section of first chapter
- after, clicking on courseware tab sends you most recent chapter, with a link to the most recent section
  (not to section because that might be confusing, and you might want to do something else (e.g. do homework instead of watch videos)
- Moved course errors into instructor tab.

- courseware index view now redirects to most recent chapter, or first
- simplify the view a bit

- was referencing no-longer-present attributes

Isolate manual git reload behind a feature flag

Feature/victor/answer export

- go through all students, all of their problems, save count for each answer
- return csv
- url exists, but no links to it yet
- Will need to integrate with Ike's new dashboard code
