Crop Bottom Texture

Adds a bottom texture to some crops

I had a problem with crops: I didn't see them from above really good, so it was hard to see where crops were planted and where they weren't. This resource pack aims to fix that, where the bottom texture is well visible from above.

Also this looks nice but still feels like vanilla

If another resource pack changes a crop's texture, you will need a separate texture for its bottom part, or else the bottom part will stay the same (vanilla)
