Massive restructuring of the collaborative quiz:
- Changed a lot of the code so it's a lot more readable, usable, etc
- Removed a lot of duplicate code
- Moving to Kinect SDK 1.7, so we don't need the Coding4Fun, etc DLLs

Still need to implement a lot of features
Added a Game Over score page.
Fixed a bug preventing two games from being played in same session
Finished removing all references to old Coding4fun DLLs
Added a check to the skeleton processing code to catch when the game has finished so no pose is required
Added a basic JSF server to provide a link for quiz nodes
