RPGBookshelves

Sorry, but this version uses a diferent file-save structure, so it won't be compatible with your old saves... Considerable optimizations: - Instead of storing and loading from/into a single large .json file, the plugin now stores each shelf on a separate .json file, the name of which already contains coordinate and world information. I think it should be more eficient this way, + it also makes it even more human readable, and you can delete or edit shelves directly from each of their files if you're up to it. - Uses Spigot's new 1.14 Player.openBook() method, reducing the code size considerably.
