Mounts & map boundings fix + Quest rates + MapleInvalidItemIdFetcher
Fixed a critical bug that would sometimes default the written mount data on the DB, causing data loss. Removed all invalid itemids from the drop data. Added quest rates. Instead of using the player's rates, quest rates stacks up with the server's exp and drop rates when giving quest rewards, making the values the same for all. Adjusted map boundings to better suit the item drop positions inside the field. New tool: MapleInvalidItemIdFetcher. It reads all existing itemids from the wz and reports inexistent itemids on the DB's drop data.
