[# 41872203]

the peer grading service

and the problem list page

The django authentication decorator login_required, redirects to
settings.LOGIN_URL. If it is missing, it redirects to /accounts/login.

We did not have the setting enable, not a proper page where to
redirect. This cause users not logged in to see a 404 error when
accessing courseware directly, by using a link or a bookmark.

- no actual functionality, but have a tab that renders static html via a view

This reverts commit 793354a0.

Ugly, ugly hack needed so that Pearson can test something today, to be replaced by a real implementation later this week or early next.

(don't worry--askbot is still dead)

- architecturally slightly questionable: the preview ajax calls goes to an LMS view instead of an input type specific one.  This needs to be fixed during the grand capa re-org, but there isn't time to do it right now.
- also, I kind of like having a generic turn-a-formula-into-a-preview service available

* should fix links without trailing slash

- move courseware wiki views above catch-all rule
- handle courses with no custom tabs

* still needs better error checking and testing

also show pid in migration and instructor dashboard views for thread debugging

- 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
