The "forum-statuses" setting:
This JSON5-formatted value defines an array of objects describing
the available statuses of forum posts. Each entry of the array must
be an object in the form {label:"X",value:"Y"}.
The label is used in the UI and value becomes the value of the
"status" tag on forum posts. Any forum post which has a status
value which does not appear in this list is treated as if it had
the first value from this list. If this setting is empty, is
ill-formed JSON, or has only a single entry then the forum will
lack the capability of setting and filtering by status.
