Survival Utilities

-Fixed throwing knife melee attack not giving any mob drops

-Throwing Knife can now be used to skin animals if you kill them with a melee attack (LMB): Pigs, Cows, Horses, Donkeys and Llamas are now all guaranteed one bonus drop of leather (useful early game when you don't have looting yet but want the bookshelves to get it)

-Moved MathHelper to MiscHelper with some code readability improvements for getting player held items. mostly unused so far

-Finally fixed the block rotator - it works fully now - it cycles through all rotations not taking into account the other properties. Doesn't work with some blocks, eg. the observer/deactivated observer. not sure why yet

Hey everyone! Sorry, it's been a while. I'm still developing this whenever I have ideas for features, so be sure to leave suggestions in the comments. Thanks for the continued support of the mod :D
