Island deletion is done a few chunks at a time per tick. Current speed
is 5 chunks per tick per world (e.g., 15 chunks per tick if nether and
end islands are used).
Chunks are deleted based on the all-time maximum protection range of the
island. This is because the protection range can grow bigger or smaller
over the island's lifetime. To ensure all possible chunks are erased,
the largest every protection range is remembered and used.
Very large protection ranges will take a long time to fully delete.
Info on islands that are being deleted is stored in the database. If the
server shuts down mid-deletion, deletion will restart when the server
restarts.
While an island is being deleted, new islands cannot occupy that spot
and the spot cannot be reserved by the admin.
In addition, async approaches to island saving and player saving were
removed. Async will be implemented another way.
Now, instead of saving the full island or player database, individual
database entries are saved instead to be more efficient.
This will load all schems in an add-on's schem folder if it exists and
associate them with this world set (overworld, nether and end). Schems
can be named anything, but the partner nether or end worlds must be
pre-fixed with "nether-" or "end-" in the filename.
Additional schems can be added by the admin into the schem folder, or
they can be stored in the jar file of the add-on. Both are supported.
No changes are required to current add-ons. I.e., there is no API
breakage here, but I would like to rename the SchemsManager method
loadIslands(World world) to be loadSchems(World world) in the future.

#361
* Added IslandInfoCommand : "/is info" or "/is who". This is basically a copy/paste from AdminInfoCommand, and it uses the same methods.
* Updated en-US locale accordingly
https://github.com/BentoBoxWorld/bentobox/issues/349
Also added pagination to protection flags and localized alphabetical
sorting of the flags.
Also added defensive code should a flag enum be removed but it is still
in the island database. In this case it will just be ignored and at the
next database object save it will disappear.
