Title: Store an optional redaction 'mode' with each redaction.

The licence-change bot considers two types of redaction, visible and hidden, depending on the
exact reasons for the redaction, but there is scope for more redaction modes in future.

I think it's worth storing these modes for now, even though they aren't currently used by either the API or the web interface.
