v167 Deprecates LinearTosRGB

[ashconnell]

Running N8AO with Three 167 results in the following error:

THREE.WebGLProgram: Shader Error 0 - VALIDATE_STATUS false

Material Name: 
Material Type: ShaderMaterial

Program Info Log: Fragment shader is not compiled.

FRAGMENT

ERROR: 0:369: 'LinearTosRGB' : no matching overloaded function found

  364:         }
  365: #ifdef DITHERING
  366:  gl_FragColor.rgb = dithering( gl_FragColor.rgb );
  367: #endif
  368:         if (gammaCorrection) {
> 369:             gl_FragColor = LinearTosRGB(gl_FragColor);
  370:         }
  371:     }

This is because 167 removed the deprecated LinearTosRGB shader function.

It was removed here: https://github.com/mrdoob/three.js/commit/132f25879f58cbc27ef432499a54eb89c5da7e40

I'm not sure what the best fix for this is but hoping I saved you some time hunting down why :)

Will push a fix as soon as possible.
