Shrimp Shader Generator FLTK2 GUI (SVN)

Updated the wood example again, using Stanford Bunny.

Had to change the wood block and rhomb tiling/painting, Aqsis & Pixie don't like binary evaluation (rhomb tiling/painting), and Aqsis was protesting a lot with the wood2 function.

Updated the wood example to use a Paul Debevec environment map (converted to LDR and envlatl, from a HDR lightprobe - www.debevec.org), that should be placed in $HOME/.shrimp/temp, or $SHRIMP_TEMPDIR if we define it.

Fixed filtered 1d noise, was "stuck" in 1d noise due to a bad #define. Added wooedpanel example.

Added bake() and bake3d() examples.

Block roll/unroll feature

Added Voronoi block using Karlsruhe (Moscow) distance metric, in complex patterns menu, with function in extrapatterns.h. Example scene committed, using cellnoise line thickness and fBm for jittering.

UI editable storage for outputs

Added storage support for block outputs

Fixed typos, and removed storage="uniform" from output types (we need to fix this, this should be accepted).
