Added generator animations in api and default generator animations in each version
Created new class to replace item holders (spinning armor stands) for generators (packet based)
TODO: Make the animation work.
Making it in 1 version, with the provided methods in DefaultGenAnimation.java of each version, should be enough to recreate the generator animations of the well known server or make custom ones (EVERYTHING IS DONE WHAT NEEDS TO BE FINISHED IS HOW TO VARIABLES OF THE ARMOR STANDS UPDATE [yaw is measured in degrees])
