Records a flag on a comment. This is intentionally flexible; right now, a
flag could be:
* A "removal suggestion" -- where a user suggests a comment for (potential) removal.
* A "moderator deletion" -- used when a moderator deletes a comment.
You can (ab)use this model to add other flags, if needed. However, by
design users are only allowed to flag a comment with a given flag once;
if you want rating look elsewhere.
