Framebuffer tickbox for LUT - 'don't apply for final render'

[DPS]

As per title, or even a 'don't apply when submitting to network rendering'

A method so that I can run my IR tests using a LUT, and I don't have to worry about forgetting to turn it off when I hit render. Similar to how the sRGB is applied to the frame buffer like a pair of sunglasses and then isn't baked into the render.
