Raza: Revamped treasure list, vendor stock and knight shield quest.

The goal of this merge is to make Raza more entertaining and educational by

- supplying the players with the reagents they need to cast their spells. Herbs, elderberries, brown, red and blue mushrooms can now be bought from Ravi. Orcteeth, fairy wings, entroot berries, emeralds and sapphires are all dropped from mummies. This roughly represents how things work in the actual game and allows players to really utilize their spells.

- preserving the players original karma, making it viable to start with Qor spells. The mummy's karma has been set to 0 and the flavor text has been adjusted to reflect that mummies are no longer evil.

- allowing players to experiment with different types of gear. Helmets, gauntlets and leather armor now drop from mummies. Small round shields, chain mails and torches can be bought from Tomas. Maces and short swords are both dropped and sold. Long swords are no longer sold. Additionally, there is a 1% chance for a jewel of Froz or a berserker ring to drop. This makes for exciting treasure and introduces the player to limited duration power ups. There is now a 5% drop chance for inkies, which is about the same chance skeletons have to drop them.

In order to straighten out the loot table, I changed the knight shields quest from entroot berries to edible mushrooms, and rewrote the relevant quest parts to reflect that change. I took the liberty to add some flavor changes. Eric now sells soup and is no longer a meanie.

I quadruplechecked everything, please tell me if I've made any mistakes.
