Grass Layer

Idea for a new block called the grass layer. Grass layers can be placed on top of regular blocks to give the top a grass texture. Like how snow layers effect dirt blocks. Grass layer can also effect stone blocks in a similar manner. But the reason I came up with this is to provide an expansion on another another post. Grass layers can also be crafted with pressure plates to create grassy pressure plates. Their like regular pressure plate but with a grass texture. This should make pressure plates more useful for traps.
