Update 'all survey data ever' spreadsheet for new schema
Update statistics view for new schema
Fix minor issues in survey views
Make survey migration not fail silently

If there is a survey without a program as its anchor, we should hear about
it.
Fix typo in QSD view render_to_response() call
Update admin app reviews module for new schema

We aren't using this and should consider dumping it.  However, we can
postpone that a little bit now that it isn't referring to the Datatree.
Update credit card viewer for new schema

The new accounting models allow for much more helpful UIs to be made
easily, but for now I'm just porting this one over.  The concept of
"complete" and "incomplete" transactions no longer exists so the module no
longer has the options.
Fix ESPUser.canRegToFullProgram()
Update UserBit import in StudentLunchSelection
Fix /manage/pages view and forms for new schema
Remove QSDMedia view

This is in anticipation of being merged with the more secure, hashed
filename version of the QSDMedia view.
Move some of render_to_response() into context processors

Detecting the current program from the URL is now easy, and adding the
expected e-mail addresses is trivial.  These should definitely be context
processors.
Simplify nav bar rendering

There is a lot of old code here that we simply weren't using.  Furthemore,
some of it depended on the DataTree:
- We no longer have Navbar editing on each page, it is handled via the
  admin interface.  This means the editing functions can be removed.
- Nav bars are no longer anchored to the DataTree, they are associated
  with categories (which used to be anchored).
Stop setting context['program'] in program module views

It's provided by a context processor now.
Filter timeslots used by student reg

We now use timeslots for teacher events as well as student events.  This
is a bit hacky, so we may want to come up with a better way of separating
them besides looking at the text in the event type description.
Fix some bugs in the student registration modules
Remove unused StudentClassRegModule changeslot view and references to it
Remove unused StudentClassRegModule swapclass view
Remove our redirect view and associated code
Fix nav bar on home page view
