Add ability to farm sunflower seeds

In game sunflowers serve no purpose but in real life sunflowers are used to farm sunflower seeds, they can be eaten or used to plant more sunflower seeds, it would be good to see that feature in minecraft, heres how i explain how it might work, you plant an sunflower seed in farmland, growth time for sunflower is the same as pumpkin, when sunflower has fully grown, you destroy it, then you will get around 4 to 10 sunflower seeds, then you can either replant them or you can roast them in furnace, and eat them.
