Verified High Quality Area Selector Tool 2022-04-11

- WorldEdit's "/wand" command now is overriden by default. There's a "# NOTE:" comment in the script for where you can remove this if you want WE's wand.
- Cuboid selector particles now show the center
- Now can select up to 30 blocks away, rather than only direct clicks (5 block limit)
- Uses "block_marker" particle effect which requires up-to-date minecraft version

Now general purpose selector wand for many different shapes!
