* Moved kernel/osl/nodes to kernel/shaders * Renamed standard attributes to use geom:, particle:, object: prefixes * Update stdosl.h to properly reflect the closures we support * Fix the wrong stdosl.h being used for building shaders * Add geom:numpolyvertices, geom:trianglevertices, geom:polyvertices attributes
