Removing all attempted methods.
Model Switcher Reasoning: The code Noppes currently has working only allows the basic EntityCustomNpc to have the GUI, Parts and Scaling. If the Model Switcher can simply replace the current model of the EntityCustomNpc then it will retain all functionality.
SkinUrl and Username are currently still broken with the new model switcher method. Will attempt to fix soon.
Added Working Model Changer that allows you to change between Default, Steve 64 x 64, Alex Models. Now instead of selecting a completely different Entity, simply go to the Model Editor to change the Model Type and Version.
