YafaRay Plug-in - reviewing for Yafaray 3.0

[david.bluecame]

Hello, guys.

For your information, you can see the progress of my modifications in the YafaRay plugin here:
https://github.com/DavidBluecame/wings/c...yafaray_v3

If you want to try the plugin, the latest version is always here:
https://raw.githubusercontent.com/DavidB...afaray.erl

I hope you find this useful.

By the way, for the Params Badge position parameter to work, you need to remove the -pbp xxx options from YafaRay plugin preferences.

In fact, I think it's best to do this in the new YafaRay plugin preferences:
* Set the path to yafaray-xml (the one in v3.0.2-beta)
* You can leave the plugins path empty, as YafaRay v3.0.2 should be able to find them automatically (but make sure it's empty and no space marks are there!)
* You can leave the options field empty as well. YafaRay v3.0.2 should just work.
