Directional Sunflowers

Sunflowers in nature tend to face towards the east to catch the light from the rising sun, but as we can not choose witch direction that face when we plant them, it greatly limits the build opportunities we have with them. This simple mods seeks to fix this issue by allowing sunflower blocks to be place in any direction by the player. This will not effect world generation, all naturally spawning sunflower blocks will continue to face eastwards.
