Latest NDE input to CTA complete

Modified New Duel Engine -> CTA data flow in order to minimize merge
conflicts with NDE and PB and add support for Joust.  Level-up via
victorious duel or other CTA/duel child events can do things like
display the portrait of the opponent (in FROMFROM scope), despite an
extra level of indirection that would otherwise "lose" the duel opponent
/ loser's proper scope.
