Bug no more.

Fixes variation scaling not working and tweaked it so much that It's practically perfect. Not really needed to lower the mobscaleswithfactor when you add many new advancements since now major story advancements are the things that increase difficulty the most. So getting 100 advancements in a random mod won't make the game unfair anymore. And instead going to the nether or the end or beating the dragon will make the game slightly harder FOREVER!!

Also added a command for my debugging but you can check it out, called "resetvariationscaling"

That's it, I put alot of effort here to fix this bug since it was an annoying one. But yeah, Have Fun!
