Adds support for pinning and closing threads to the current REST APIs for discusions.
Adds a preview_body field to the thread response that contains a truncated version of the raw body with tags removed so it can be shown in previews.
Adds a field called "can_delete" to threads and comments that signals if the current user is able to delete that resource.
This change adds three new filters to the threads API. They are:
* Filtering only threads that are flagged for abuse
* Filtering by the thread type (discussion or question)
* Filtering by the thread author
In addition it also adds a new ``abuse_flagged_count`` field for threads. It
returns a count of the number of comments in a thread that are flagged for abuse.
This is only visible to users that have moderator privileges or higher.
Finally it also adds a ``abuse_flagged_any_user`` field that is set if any user
has flagged a thread. This field too, is only visible to moderators or above.
