Dispensers, Cocoa Beans and Brown Dye

Currently Cocoa Beans are the only source of Brown Dye. In the current game there is no way to automatically farm Cocoa Beans using Redstone. This makes the colour brown rather time expensive to build with as I have found out in one of my recent builds. I suggest making it so the Dispenser when facing a airblock next to a Jungle Log can place any Cocoa Beans inside it on the Jungle Log. This would allow for automatic farm designs both AFK and Bone Mean Accelerated Growth versions. This would greatly bring down the cost/time of making cookies and brown dye.
