Upgrading gunicorn to latest
Use real templates in forum NewPostView tests
Add cohort selector tests in forum NewPostView
Use some real templates in forum list view tests

Unfortunately, one template (thread-list-template, defined in
_thread_list_template.html) still relies on complex Mako processing, so
that is still being mocked in the tests.
Improve thread list view tests

An obsolete test case was passing because the assertions were too weak,
so the assertions are improved and the test case removed.
Temporarily disable bulk operations b/c old mongo
does too much work on exit and doesn't handle nesting
Make primary button focus state more pronounced
increase contrast of submission_feedback text
Ensure forum nav cohort selector works correctly

One minor case is fixed (to pass "" instead of "all" as the group_id
parameter to indicate viewing all threads), and tests are added.
Update mongo counts.
Move more forum nav rendering logic to front end

The cohort selector is rendered only for a privileged user in a cohorted
course, and that logic is now in an Underscore template instead of Mako.
remove course-id visual column from the list of coupons as it's useless information here and prevents overflows from happening
don't hard code the shoppingcart order confirmation page to use settings.xxx, allow for microsites to override
