Raw ore block functionality and texture

Raw ore blocks are an excellent idea, but the textures have proven difficult to differentiate them from "bean blocks". I'd like to propose that these blocks function similarly to cake blocks and layered snow blocks. Whenever you right click a space with a piece of raw iron, it will place a part of the block. Then, whenever you right click the block with an empty hand, you collect a piece of raw iron. Of course this would function with raw gold and copper as well. This way, the texture could be more of a layered look instead of "beans".
