v20.1 [v12+] Difficulty Modes 1.1.1

This script is for Pokémon Essentials. It allows an easy way to make difficulty modes like the ones on Key System in B2W2.

A difficulty mode may change:

1. Wild Pokémon levels
2. Trainer's Pokémon levels
3. Trainer's skill level
4. Trainer's money given
5. Trainer definition (define a different trainer entry in trainers.txt)
6. Exp received

Tested on Essentials v19.1 and v20.1. More versions (v12) on link. If this script isn't working on latest Essentials version, please inform on this thread.
