- added support for the following skyblock plugin: FabledSkyBlock.

- switched from json to yaml
-> data is no longer stored in the .json file. Instead, it adds all generators to the config.yml just like CustomOreGen does. The plugin will automatically convert your old AdvancedOreGen data file to the new yml file.

- added warning messages when a generator was not setup properly

- fixed performance issue for 1.8.8 servers
