Option to rename the vertex color data layer used by Ocean modifier for foam. The modifier outputs foam values to both textures and a (temporary) vertex data layer. This layer was unnamed before, which makes it impossible to access in shader nodes. Now the user can input a custom name in the modifier panel, then use that same name in a shader input node to access foam values.
