YafaRay plugin; update roadmap and change list

[micheus]

Edit:
Btw.. You can use this info from:
wpa:camera_info([pos_dir_up, fov, azimuth, elevation, tracking, distance_to_aim])

thanks.
Now you pointed it, I noticed that Kerkythea is already using it for that.

We have a very strange way to set the DOF for use with renders, but it certainly works. We need first set the Aim, after we can set the camera location and then we save the view (if we set the Aim at the end we'll move the camera).
