Negating permissions for a complete shop section like 'EconomyShopGUI.sellallitem.farming' wouldn't disable per item permissions
Changed:
Specific item permissions will now correctly inhert the section's parent permission Example 1: When disabling permissions to sell an specific item using '/sellall hand', the permission 'EconomyShopGUI.sellallhand.<section>.item.<permission>' needs to be false Example 2: When disabling permissions for an specific item using '/shop', the permission 'EconomyShopGUI.shop.<section>.item.<permission>' needs to be false
