Default World Generator (port)

First Testing Release for v2.0

Many changes (and sure to be cleanup/beta soon)

* Multiple Defaults support (example skyblock vs wastelands)

* Can change default state of structures (dependent on the underlying generator)

* Server Init Commands (configure per default one or more commands, as in command block commands) to be run when a server starts/restarts (or when you launch a single player world)

* DataPacks.  These are files that are injected into a save file, such as custom loot tables, these will be automatically updated when a modpack updates in the relevant save files.  This also can be used to import pre-generated worlds, just ensure the world type is locked and the generator/customization/seed are all set to the same values as when you generated the pre-generated world.

* Copy world uses the same customization settings as the original world

Warning:

The config only saves when you press save, if somehow you exit the config menu without pressing save you will have lost your work.. (aka don't press escape in the menus its not properly mapped yet)

Other Notes:

* All configuration must be done in the client (mods -> Default World Generator-Port -> configure) old config files no longer valid

* If none of your configurations are "listed" the first one is the default and automatically selected on "New World"

* the UUID is the real identifier in the world save, and links the Server Init Commands/Data packs to the world, (unlisted worlds let you maintains such data for users that started with older worlds you do not intend new users to re-use.. note the recreate button will use the unlisted world information.  (if the UUID in the world is not found in the config, it will re-default to the first one in the list regardless of if its listed or not)

* If you want a custom png for the multiple world selection make it square (actual size is 32x32 units, for the same resolution as the font) it goes in config/defaultworldgenerator-port/<imagename>.png

*the files for the data packs go into config/defaultworldgenerator-port/<datapack name> (the default data pack is common, the assumption is this will be used for most elements, but if say you have an expert mode it might be called "expert" currently pack names must only contain [a-z0-9_]*

Report any issues, but this is a work in progress thus may need a revision or two before is reasonably user friendly.
