YafaRay plugin; update roadmap and change list

[povmaniac]

Is there a good reason for moving the background settings to Render options???

Yes. It is the correct way in which YafaRay calculates the lighting.
Perhaps you do not know Python, but it should look a little in the files of the exporter for Blender.
The exporter, must be the bridge between the modeller and the engine of render, giving him the information adapted to obtain correct results.
