wraitii 01a8138780 Water GLSL shader improvements around reflections and whitespace fixes. 
This improves refractions around entities close to the surface, such as
fishes, by handling depth better and by clipping the water plane a
little lower.

This uses the skybox for reflections when refractions are enabled but
reflections are disabled, making it possible to play with reflections
disabled without having super-ugly water (arguably a performance
improvement).
