I do need current_sector, fixed Trade Report bug.

I need current_sector, so I know whether or not I need
to move to get to the planet.

If you trade with StarDock and trade report, it crashes
because it doesn't have a class.  (It is class 0, but
it doesn't show on the trade screen.)  Also the find
next good trade has same issue.  Fixed.
