Fixed signs.cfg so it no longer generates signs for non-existent buildings in Magincia.
Changed create world so that it no longer generates decorations for non-existent buildings in Trammel Magincia and so it no longer creates rubble and ruin in Felucca Magincia. Create world will now instead generate player vendor tiles for the new Magincia Bazaar, as well as create decorated vendor "stalls" in the previously empty dirt patches. Also, it will generate signs and doors properly for the few remaining buildings left in Magincia. Factions and the town Sigil/Monoliths will still generate properly in Felucca, this update simply makes Magincia more "osi-like".
