~ fixed an issue with the 1.16 compatibility
It was not possible to
sign / unsign an item because of a deprecated method I've used in the code.

I am very sorry for this unconvenience!
Previous:
getItemInHand() & setItemInHand()
Now:
getInventory().getItemInMainHand() & getInventory().setItemInMainHand()
The code is now fully corrected and will work 100% again
Compiled with Java 15
I wish everyone a wonderful X-Mas!
