Shulko adds a real purple shulker box, matching the color of every other dyed thing in the damn game.

Vanilla purple shulker boxes still exist, but are now undyed shulker boxes, and are still the crafting result for the main recipe. After dyeing a shulker box, the only way to make it into a vanilla purple shulker box again is to right-click it on a cauldron. This will remove the dye and consume a level of water. Contents will be retained.

Additionally, vanilla purple shulker boxes are renamed to just shulker boxes, reflecting the fact they're now considered undyed.

Compatible with Quark just due to how Quark works. Other mods should be compatible as well.
