performance improvement

---- 2.1.5e - The MASSIVE update. ----
HUGE CHANGES. I don't think I'll need to update DupePlugin for a very long time after this, I'll just change it as the source code of minecraft changes. The plugin is now PERFECT.

Now FULLY compatible with 1.8-1.16.

---- main ---
EVERYTHING is configurable. Down to the bone. Even the color of logging.

---- logging ----
logs color-coding based on an items color (configurable)
logging items in shulkers (configurable)

---- duping ----
duping minimum / maximum random added (configurable)
limited-items added (max stack size) (configurable)
illegal-items added (undupable / removing, fully configurable)
shulker duping is disable-able (configurable)
checking inside of shulkers for illegals (configurable)

This version is already out and deployed on 8b8t.xyz

Support from 1.8-1.16 should be added
1.12 & 1.16 verified versions and work

You now have to repeatedly click instead of click once
It also has a process in the works to remove the item used to dupe
