code is now more OOP

support for version 1.8+
note:
booktype is for 1.10+
potion's color is for 1.11+

added a permission for each sub command
example: to rename an item you need permission itemedit.rename node
itemedit.* and itemedit.admin grants all the permission

interactive interface, by moving the mouse over the help you'll see description and tips, by clicking the command on the help it'll paste the command in your chat bar

dynamic help, will show help only for the sub commands you have permission to execute
