We should be able to throw Result or ResultSet instances at event subs
Generate events after Comment insert.
Operating straight on the ref call not working - assign then operate.

Currently, I do not know why this is.
Adding timestamp to Event table
Removing old add_event call from Result role
Filtering on forum id before processing all comments event.

Should only add this event if there's a parent_id - having none denotes
a thread starting comment which should be handled in thread events.
