Changes Log:

1. Fixed Fresnel attenuation for specular/transmitted lobe (matte/phong material).
2. Added Ashikhmin material.
3. Obj file import parameter addition "Group by Material"; by default the importer will merge all meshes with same material.
4. Ability to preview original model in material editor.
5. Added progress bar when building previews in material library.
6. Added Lafortune material sampling (still importance sampling is missing).
7. Correction of tone mapping in auto image saving for progressive renderings.
8. Added dispersion with bidirectional path tracing.
9. Changed dispersion factor to correspond to standard Abbe number.
10. Re-assigned toggle of wireframe/solid OpenGL view from ´S´ to ´V´.
11. Fixed cylindrical/spherical projection (bug shown in bipt).
12. Many small bug fixes!
