Added Simple Image Background Exporting for Yafray

Browse Source 
Add an image texture to the world (in any channel, the first one with an image will be used) and it will be exported as an image background
   The texture 'bright' slider is connected to the 'power' variable

If the image selected ends in hdr, it will be exported into an HDRI block.
   The texture 'bright' slider effects exposure adjust (it is slider value - 1) so a value of 1 == no expousre adjust. (this needs a better solution in a later    implementation)

// if no GI used, the GIpower parameter is not always initialized, so in that case ignore it (have to change method to init yafray vars in Blender)
