Merchants: alchemy vendors wrong

[emubird]

Alchemy vendors need fix asap.

The two alchemy vendors in Oggok have the wrong inventories for alchemy ingredients. They should have the basic inventories of Dargon and Spirita in Halas.

The two alchemy vendors in Grobb have duplicate inventories of each other for alchemy ingredients. They should have two different inventories, the same basic inventories of Dargon and Spirita in Halas.

Also, the troll basic potion merchant in Grobb is missing generic herbs and potions.

Right now only the Barbarian shamans have the ability to skill up alchemy correctly, giving them an unfair advantage over their evil counterparts.
