Lukas Toenne df79ab5a77 Added Object Info node implementation for OSL. This uses an additional attribute check in the osl_services callback for special attribute names related to objects:
* std::object_location
* std::object_index
* std::material_index
* std::object_random

Other object-based attributes can be added for particle info in the same way.
