Many changes & fixes... - shader updates are delayed by .25 seconds to avouid UI freeze - fixed GraphNode initialization upon loading - started obsoleting get_source_rgb and get_source_f functions - updated colorize node to use gradient - image node can now be loaded/saved - removed iqnoise node - rewrote perlin shader to support a seed parameter (seed is calculated from the node's position, so just move it to reseed) - Added voronoi noise node - updated code to use % formats instead of concatenating strings (should solve type problems in shaders) - reworked the context menu (now has submenus) - fixes in the gradient editor

Cleanup and renaming Moved Material Spray to another repository. Renamed the addon directory to material_maker

Updated bricks and voronoi nodes to provide several outputs Updated base node class to support several outputs. Now bricks support 2 outputs : greyscale depth map, and (random) brick color. Now Voronoi supports 3 outputs : center distance, edge distance and cell color. Updated bricks example to use brick color output.

Added a generic node type Updated all nodes so parameters are located in a "parameters" variable. Started writing a generic node model whose behavior is defined in a json file. Should be able to replace all generators so far. Wrote json files for bricks and noise nodes. Started preparing a custom node.

Refactoring, new noise node and blur updates Added a noise node (paints randomly pixels in black or white). Modified blur so direction can be selected (horizontal, verticla, or both). Updated code to use string formats instead of conversion + concatenation.
