Shrimp Shader Generator FLTK2 GUI (SVN)

Changed the Blinn specular term name to Phong-Blinn, to avoid confusions, since this isn't neither the Torrance-Sparrow model with Trowbridge-Reitz distribution (C3) nor the Blinn model for dusty/cloudy surfaces, but the Phong model, using the half-vector, instead of the reflection vector.

Fixed undefined references to the AOVs, in non-surface shaders.

Preview and Export functions output the rendering command list in a file

Block info dialog shows author's name

Updated sources to latest GCC (4.3.2) and FLTK 2 (r6483)

Updated the Cook-Torrance block, to use the complex Fresnel function, instead of the normal fresnel(), and added extra parameter for extinction coefficient in the respective block.

Changed the hyperbolic sine, cosine, tangent blocks, to use the functions defined in the shrimp_helpers.h header, instead of block code.

Added complex arithmetic blocks and complex Fresnel block (unpolarized light), using functions defined in odwikicomplex.h header, from the Odforce.net Odwiki, and the Odwiki BRDF article, by the Odforce community and Mario Marengo. Added respective header, odwikicomplex.h, updated shrimp_helpers.h for hyperbolic sine, cosine, tangent, instead of being defined in the their respective blocks bodies. Updated the trace() block for a typo and incorrect macro definitions and checks. Many thanks to once again, Mario Marengo, Jason, and the Odforce and Odwiki community.

Changed current shaders' XML code tag from 'code' to 'rsl_code' to easily support other kinds of renderers in the future

Updated symbols definitions, so that we don't redefine macros (and have the subsequent warnings/errors).
