YafaRay plugin; update roadmap and change list

[povmaniac]

The images with 'low dynamic range' is not good methode for IBL.
You can use more image types.. if add filters to 'extensions', browser code..

Code:

BrowsePropsHDRI = [
        {dialog_type,open_dialog},
        {extensions,[
            {".hdr",?__(56,"High Dynamic Range image")},
            {".exr",?__(95,"OpenEXR image")},
            {".tga",?__(1096,"Targa bitmaps)}"
            and more......
        ]}
    ],

.. but is not good idea
YafaRay need the high range info for work better with the image background.
