This adds a new secure_uploads_pm_only site setting. When secure_uploads is true with this setting, only uploads created in PMs will be marked secure; no uploads in secure categories will be marked as secure, and the login_required site setting has no bearing on upload security either. This is meant to be a stopgap solution to prevent secure uploads in a single place (private messages) for sensitive admin data exports. Ideally we would want a more comprehensive way of saying that certain upload types get secured which is a hybrid/mixed mode secure uploads, but for now this will do the trick.
