Small, Variation, Update

Added and Remembered to add some little things and also little changes.

• Renamed Older Gamerules to start with entity in the gamerule menu instead of mob for better clarity.
• Slight Rework to the Mutations Effect which makes them slightly balanced. Instead of being completly random, a value is random which determines how bulky or light you are. This was how I oringinally wanted the effect but I couldn't figure it out, until now.

A better explanation for this effect if you don't understand, if you have more health than youll be slower and heavier, if you're quicker than you'll have less health and be lighter.

• "Added" dragonEggIncreasesVariation gamerule which increases the normal and powerful variations gamerule whenever a player picks up the dragon egg. This is off by default and a bit buggy.
• Powerful Mobs now drop 1-2 Powerful Dust instead of just 1.

Maybe other little bug fixes too but thats about everything. Mod is in a gooder state now so yeah, Have Fun! Oh and Wahoo!
