Replaces Live TF2 viewmodel arms with TF2 Classic's viewmodel arms.
Replaces Live TF2's c_model arms with TF2 Classic's c_model arms.
This DOES NOT change the TF2 Playermodels' textures into TF2 Classic's, this is ONLY the viewmodel arms.
I've also copied the material properties over from TF2 Classic.
