[1.30] Possibly unintended behavior in Auto Trade (Galaxy)

[VladWard]

When given the Auto Trade (Galaxy) command by right-clicking in sector space on the map, the traders in question appear to use that sector as a fixed point in their trades.

For example, if the Auto Trade (Galaxy) command is given by right-clicking within the Holy Vision sector, then all trades executed under that command will either start or end in Holy Vision. The trader may leave the sector to purchase a good elsewhere (say, Black Hole Sun), but it will return to sell the good in Holy Vision.

This results in Galaxy Auto Traders performing a large number of barely profitable trades after their "home" system has reached product saturation, despite significantly better trade opportunities existing elsewhere.

Unmodified game. 1.30 stable/live release.
