JustQuests

Added

• Settings for every world: config/justquests.json. Any key of a world's settings.json set there applies to every world of the game or server and wins over the world's own file, so a modpack can ship, for example, "generatedQuests": false. Commands can't change a key set there and say so. The file is created with an explanation on first start. (Requested on GitHub.)
• Folders are categories: a quest in a sub-folder of a datapack's justquests/quests/ (also the plugin's quests/ folder, or a key like "mining/iron" in custom-quests.json) that names no category gets the folder as its category - quests/mining/iron.json is in "mining". Deeper folders only sort the files. (Requested on GitHub.)

Changed

• mainQuests: false (and /quest mainquests off) now hides only the 25 built-in quests; quests from your own datapacks stay. Before, it hid every datapack quest. Mod and plugin.
• A category without a translation reads in chat as it does in the quest book: "mob_drops" shows as "Mob drops".
