Implement import & export support for "PBR extensions" in .mtl files (T101029, also fixes T86736). Newly supported parameters: - Roughness (Pr, map_Pr) - Metallic (Pm, map_Pm) - Sheen (Ps, map_Ps) - Clearcoat thickness (Pc) and roughness (Pcr) - Anisotropy (aniso) and rotation (anisor) - Transmittance (Tf / Kt) Exporter has an option to enable these additional PBR parameters export; defaults to off since not all software understands that. Exporter UI tweaked and all material-related options were put into their own separate box. Added/extended test files in Subversion repository for test coverage.
