* Shader script node added, which stores either a link to a text datablock or file on disk, and has functions to add and remove sockets. * Callback RenderEngine.update_script_node(self, node) added for render engines to compile the shader and update the node with new sockets. Thanks to Thomas, Lukas and Dalai for the implementation.
