This converts the deferred lighting shader to use uniform buffers for the dynamic data sent to the GPU while rendering the lighting effects. This doesn't affect performance but the deferred lighting code is a nicely isolated piece of rendering code where I could test how the rendering code could use the uniform buffers. This is related to #910.
