Adds Protoceratops to Minecraft! Based on this accurate Protoceratops reconstruction by TheMorlock on Deviantart:

Note: It requires modding to give it a large frill, more beak-like mouth, quill-like filaments on its back and tail, and a long, visible tail. Also note that the wool is supposed to mimic the reconstruction's feather covering, and can be sheared to show the animal's color like in the reconstruction showed above. Its black and white eyes are on both sides of its head, near its orange and grey nostrils on the front.
