Pumpkin and Watermelon Vines?

This would be a cool features. Horizontally spreading multiblock pumpkin and watermelon vines. Maybe fancy up vanilla vines some, while you're at it! Could also make glow licken a bit fancier, if you wanted, though there isn't a lot to do there - just make multiple versions of the block, based on thick it's grown. You could also work on Coral, if you wanted to.
