* Fixed problem with liquids, now they can't spread outside island
* Added config create-limit - you can limit how much islands player can create
* Added command /islandev clearcreatelimit <player> - clear player limit
* Added list in config for all available schematics (if you want to have more than one)
put your schematics on that list and make sure that your players,
