Title: Implemented 'light near start' for EDFs

I've added a setting to EDFs for "light near start". Points that are closer than this distance will not get lit by the EDF.
A side note: In Luxrender this feature is called "light near start" but in arnold it's "near attenuation", which might be a better term for it. What do you think?

Here are two images for comparison:
