Webhook delete event type

[FieldofClay]

It would be great to expand the event types the webhook functionality offers, by adding the delete event. I'd envision it containing the contents of the deleted row, similar to the create/update event types.

It may also be handy to have the event type as a field within the webhook payload, just to remove any ambiguity around what the trigger was.
