Oops
Fixed a wand issue
Added /w pos1 w.i.p., cleaned several things
Added BlockList random blocks format parser
W.I.P. subcommands
Finished /w cyl
Added websites in plugin.yml as the repo link; WorldEditArt: added /w test
Added update parameter for spaces utils
Added pattern implementation
Added $update for randomPlaces()
Finished /w test and /w set
Cleaned up Main.php using a vacuum cleaner
WorldEditArt: /w wand and /w macro (W.I.P.)
