feature(cli): Added a CLI version of WorldEdit, and allowed most commands to be run from console (#508)

* Re-do commits to avoid awful rebase

* You can load and save a schematic file now. Still gotta setup ability to use commands as a console actor.

* Add a world override concept to LocalSession, and allow a lot more commands to be performed by actors.

* Fixed commands, and set the loaded schematic as the world override in CLI

* Properly load tags

* Added 1.14.4 data values

* Allow a majority of commands to be performed by the console.

* Fixed a lot of PR requested changes

* Added a Locatable interface and use that for getting the location of the player in commands.

* Added script support. Currently requires a newline at the end of the script.

* Shade everything to allow this to run locally - should probably minimize this to an extent later.

* Actually hook up the version

* Added a //world command to set the override

* Fixed a missed checkstyle issue

* Added CommandBlock support to Bukkit

* Make command block support configurable

* Minor cleanup and implementing a few of the final functions

* Fixed most issues from PR

* Improve UX, saving is now automatic and unknown command messages show

* Better save docs and support any clipboard format

* Include the entire formats list

* Arrays.copyOf

* Clear the world override if the selector is called on another world.

* Update logging extent to allow basic logging with non-player actors
