Merchants: Medium quality ores

[SchadenFreude]

Merchants that are supposed to carry this, especially in evil cities, are not. Instead, they have "Clay" ores when they should have the medium quality ores. The only vendor that could be located which carries the medium ores was in north freeport, in the midst of paladin country. Interestingly, those vendors were "Indifferent" to a troll SK, when they should have been dubious.

This makes it almost impossible for a troll to make fine plate.

Please put the medium quality ores back onto the vendors in Oggok and Neriak.
