ADD : Now the Executable Items cant be used to craft vanilla items (1 new locale message "cancelCraft")

ADD option item : unbreakable true/false

CHANGEMENT VERSION [1.13 - 1.16] : Now the verification of if it is a ExecutableItems is not by the name/lore/material but by invisible Attribute so you can make EI with blank name and blank lore (to blank just put &7 or another random color)

Fix nullpointer exception if you run ExecutableItems on spigot 1.16 server.

Good dev ! If you have suggestions or issues join the discord
