null shader issue

[plaidpants]

I don't see how public Shader shader; ever gets set. The editor script hides this variable and it cannot be set to the SENaturalBloomAndDirtyLens.shader. When OnEnable() is called the new Material(shader) always gives an exception because shader is null and then the rest of the code falls down after that. If I manually set the shader to SENaturalBloomAndDirtyLens.shader everything works. I suspect previously created cameras have the variable set correctly and that's why the demo scene still works.
