Ocean Shader

Body: 

 For the past few weeks Ryokeen has been hard at work adding and optimizing shaders for ESF. One of the latest additions is a wave generator. The new shader gives ESF environment artists the option to add ocean like water to maps.

During initial tests the ocean shader has shown a performance increase over the older "flat" water shader. The system uses a grid of approximately 50K polygons to generate the waves. This can be reduced to meet the performance requirements of lower-end machines. Also, the system implements a level of detail system that increases the amount of detail a player sees the closer they get to the water.
