* Added some new integrator parameters to the xml reading.
* Added ability to specify window width/height, if not set it uses film/camera width/height.
* Added back the xml exporter script from cycles branch, with modifications to hock up into the UI. To use it, copy the script into 2.61/scripts/startup.
Note: This is intended for developers for now, but the standalone Cycles app has potential to be used as benchmark for example.
