MoveDispatch: replace slow move line. Fix visual.

When they display <Auto Pilot Engaging>, they clrscr + home cursor.
The clrscr is eaten, and now I eat the home cursor so we don't
have text upon text.

Initial notes on trade_pair.  The code needs to be redone, so it
looks at the real port data to find real trades.
