Late Spring Cleanin'

A few fixes and changes and a new gamerule!

• Added a new gamerule "Lightningcausesmutations" which causes lightning strikes to cause mutations for a brief time (this is off by default)
• Powerful Mobs are now slightly stronger, faster, and regenerate faster now
• Powerful Mobs will now only drop extra experience and dust if a player or a player's pet kills it. I can remove this if ya don't like it
• The Powerful effect now lasts forever instead of just a large number, hmph
• Powerful Mobs no longer make a dumb loud sound when regenerating, it is now a quieter sound
• Powerful Dust is no longer used up while in creative
• Powerful Dust can now be eaten even if your not hungry
• Fixed Powerful Mobs sometimes refusing to die
• Fixed the Powerful Effect sometimes showing up when it shouldn't
• Fixed Powerful dust powering up mobs that are already powered up
• Fixed the Powerful effect from showing particles even if it was taken off (hopefully)

Lots of quality changes here and sorry for no updates on any of my other mods, so just enjoy this update. Leave Comments if you want!
