[CGMZ] Encounter Conditions - Version Beta R6

Hi all, today this plugin was updated to version BetaR6!
This version adds a custom JS condition for your encounters. This should allow you to make any condition you want, only limited by your JavaScript skills. Of course, I will still be adding more no-coding conditions in the future. This is a way to allow you to add your own conditions without needing to wait for me to update this plugin with a no code solution.
