Version 20180605-snapshot for Minecraft 1.12.x

• Enchantment cracking is no longer a hidden feature, since it has been public for a while now
• Add ans to /ccalc
• Add ability to disable rendering of certain or all entities
• Add ability to select an area with cselect or with a wooden axe
• Add cfill, cclone and cstack. cfill and cclone act like the vanilla commands except there is no fill/clone limit and they work with selection. cstack works like the worldedit command.

Known bugs:

• /cselect deselect shows an error message even when it succeeds
• Rotational arguments in /cstack aren't parsed properly, but they're optional so for now don't use them
