This is the first view being converted which is truly "read-write". The

"All Status Reports" page lists all of the status report due dates for

active groups, and shows which reports have been submitted and which

haven't. It also allows editing existing due dates, creating new ones,

and deleting them.
While I was doing this, I made some improvements to the page:

Instead of listing out students in two separate columns (for submitted

  and not submitted), I've combined them into a single column and faded

  out the avatars of those who haven't submitted yet. This is much easier

  to read, very visually attractive, and shortens the width a lot, leaving

  a lot more room for the editors of the due date and groups columns.
The width of various columns and editors has been tweaked to be a lot

  more usable.
I've worked around a bug in bootstrap-datepicker that was preventing

  the actual contents of the datepicker from being shown.

Added, edited, and deleted status report due dates. Saw that things

  updated as expected and sent the correct data to the server.
Checked that links to existing reports worked correctly.
