exclude from indirect lighting checkbox on emissive material.

At the moment it's impossible (to my knowledge) to use an emissive material without a ton of noise being introduced. Besides my previous request to have a 'direct lighting' checkbox for the emissive material (so it acts as a proper light), it would also be great to have an 'exclude from indirect lighting' option (as this is where the noise comes from when using the emissive material).
