[CGMZ] Enemy Upgrade - Version Beta

Hi all, today this plugin was updated to version Beta!
This version adds an integration with [CGMZ] Difficulty, so your enemies can automatically be replaced with different versions for different difficulties. This can allow you to totally fine-tune enemy stats and other properties for different difficulties.
This occurs before the special version check, so your various difficulty versions can still have special version chances.
