Shrimp Shader Generator FLTK2 GUI (SVN)

Added example to use tangent space normal maps, and an included tangent space normal made (gimp generated & normalmap plugin, sobel 3x3, from capillary reaction diffusion texture/Turing pattern). Texture in .tif format, the example reads it from $HOME/.shrimp/temp/ , so the installer should copy all the textures needed to this location.
