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.

One minor case is fixed (to pass "" instead of "all" as the group_id
parameter to indicate viewing all threads), and tests are added.

The actions are now consolidated in one location for each piece of
content. Primary actions (vote, follow, endorse, mark as answer) are
buttons, and secondary actions (pin, edit, delete, report, close) are in
a menu. This also includes improved front-end error handling for the
actions and significant test cleanup.

This feature is supplanted by the flagged option in the filter menu,
which can work within topics as well as across all topics.

The menu allows filtering to unread, unanswered, or flagged threads.
This includes passing through the appropriate query parameters to the
comments service.

A link to show the comments appears in their place.

Also change server to pass post type through to the comments service.

The previously existing checkmark for threads with endorsed responses is
removed, as it is mostly redundant.

Responses to question threads can be "marked as answer" instead of
"endorsed".

Each thread's type is now included in its post details, and question
threads have marked answers shown immediately below the body of the
initial post.
