Shrimp Shader Generator FLTK2 GUI (SVN)

Added the Strauss empirical BRDF to the local illumination models header, as well as the respective xml block.

Added the Banks fast anisotropic shading model block.

Added the Banks fast anisotropic shading model in the shading models header, and the respective block.

Updated shadingmodels.h to use the fixed Smith attenuation term in the Cook-Torrance model.

Updated distributions header to fix the Smith attenuation term (product of 2 attenuation terms, between incident vector and microstructure normal, and viewer and microstructure normal).

Implemented the Export Scene menu

Added tooltips to all the main window's widgets

Removed anisoct block, since it's included in new Cook-Torrance block.

Updated fractal.h for unitialized variable warning in voronoi functions. Added simple shadeop to access glibc's complementary error function, used in the Cook-Torrance shading function, for the He-Torrance geometric attenuation. Updated all shading models in respective header. Updated Cook-Torrance block to add access to multiple microfacet distributions, and geometric attenuation functions, defined in distributions2.h header. Updated shading models header to add new Cook-Torrance model. Improved all other shading models. Removed anisoct block, since it's not part of the new Cook-Torrance block.

Separated type and storage in 'add input' dialog, added checks for empty names
