RAGE and Buddy Knavery II upgraded

Buddy Knavery II and RAGE have been upgraded to Silverlight 5 and I added a few improvements while I was at it. RAGE now leverages Managed Extensibility Framework (MEF) for the discovery of scenes, character controls, ScriptActions, and more. Also, the low-latency XNA SoundEffect class is now implemented for the playback of WAV files.

Head on over to the RAGE area for more details, particularly the updated article on setting up the environment and extending the engine.
