Loop over the uniforms of the stateset of the node and set them on the passed in shader.

delete the entries of programs to cached uniform locations must call when cloud layers are deleted, atmosphere deleted, triton drawable cleaned up.

used to cache the shader uniform locations to avoid glGetUniformLocation calls Saves somewhere between 1-3ms and reduces variability of frame time with Triton and Silverlining Tried caching the uniform values as well but that did not seem to make a difference.
