- Consistent behavior for bulletin boards for course configuration:
exclusion from contributing to discussions (role or user-based) -- pch priv.
- Textarea for posting not shown if pch priv prevents posts by current user.
- Show "Discussion closed" if unable to post.
- If board is a group board and user has pgd priv for the group, this
trumps exclusion based on pch priv.
