Changes:
- Fix several issues regarding world generation and island disband
- Update to latest version of SuperiorSkyblockAPI and AdvancedSlimeWorldManager API.
- Add config options regarding enable and unlock worlds (normal, nether, end)
Issues:
- Due to method from SuperiorSkyblock2 being called very often, everytime you disband an island, the island worlds will be recreated again (empty world) with the same island uuid that just got disbanded.
