Adds:
     - Coral Growth
     - Coral Grown
     - Coral Harvestable

To Use:
     - Start by breaking "Coral Reef" blocks
          - These will drop you 3 "Chunks of Coral" of the given color

     - Grow a "Coral Growth"
          - Place a Chunk of Coral (of any color) into a barrel full of water (50L)
          - Seal the barrel and wait 48hours to get a "Coral Growth"

     - Place the "Coral Growth" down
          - It must have a SOURCE WATER block ABOVE it and ON it to actually stay
               - Note - Water flowing above to on top of it DOES NOT count, both layers must be a SOURCE WATER to count.
          - After 5 in game days (regardles of being loaded or not) the Coral Growth will change into Coral Grown
          - After another 5 days in game the Coral Grown will change into a Coral Harvestable

     - Harvest the Coral Harvestable (with a knife)
          - This will supply you with 3 chunks of coral of that color
               - Your Coral Harvestable will downgrade to a Coral Grown and you will have to wait another 5 days to get another Harvestable Coral
               - If you break the Harvestable Coral it will drop a Coral Growth to replant and 3 chunks of coral
                    - the downside to this is that you now will have to wait 10 days for the coral to grow fully back instead of 5.....so harvest unless you are looking to move your coral farm!
          - Store the chunks of coral or make another coral growth and grow your farm!!!

This method is soley to supply a sustainable way to create Coral Cobblestone, I didnt want to have to completely destory reef systems in order to get a lot of this block, and I thought coral was cool to grow/farm!!!
