Need to combine all xna and silverlight example projects


Need to create a example browser rather then creating projects for each new example project that gets created. This will help reduce the number of projects in the solution and help tidy up it up better. Neds to be done for both Silverlight and xna examples respectively.
The browser app should also incorporate mef to load external examples into the browser so third parties and create there own examples and integrate it into the example browser.
