Issue Description:

When editing a Biomes json file any changes made will be rolled back on launch.
I tried doing something as simple as changing dirt to snow in a biome and it was undone.

Steps to reproduce:

1. Edit any Biome .json
2. Launch the game

Affected Versions (Exact numbers, do NOT use "latest"):

• Biomes O' Plenty: 7.0.0.2289
• Minecraft: 1.12
• Forge: 2413

This is intentional, those files are just meant to show the default values and structure of the json files, so you can copy certain parts into a file in /config/biomesoplenty/biomes based on what you want to change. See https://github.com/Glitchfiend/BiomesOPlenty/wiki/Configuring-Biomes for a better explanation

Thank you very much.

My bad =P
