Added Magincia Bazaar support

Added Magincia Bazaar scripts to support player vendors in New Magincia. The system is OSI-like, and vendor employment contracts can be bought from a Vendor Mall Manager and placed on any player vendor tile (tiles have to be placed manually by GMs.) The system supports player vendor tiles being added anywhere, but for OSI-likeness the vendor mall manager should be placed in New Magincia. The small, square patches of dirt are areas where player vendors are supposed to be placed. Also included in script is bazaar addons, which are designed to be specifically sized to decorate the dirt patches in Magincia.
