Beach Biome Additions

Hello, I have a few Ideas that I think could make Beaches more interesting to visit.

• Add a new kind of tree type, called the Palm Tree. It would use a new kind of Log and Leaves. I think the set of wood blocks that come with the new log type would have a very tropical style.
• On the Beaches, add waves that rise and fall on the sand that also give a sound effect to give a more calming feel. Maybe even add a ability for items to sometimes wash ashore.
• Add a new mob to the Sandy Beaches, called a Sandpiper. They will run across the Beach in groups and will peck into the ground. Sandpipers will be bred with Cod.
