PlatformSystems are no longer AddIns. This doesn't mean, that you can't load them dynamically. The handling is just different. There's only a single PlatformSystem available for each platform ANX runs on. This one is auto loaded. If it doesn't exist the game doesn't run. The reason for this is, that we will move the AddIn system from ANX.Framework to the specialized PlatformSystem. This is necessary because we want ANX.Framework to become platform independent. The AddIn system is different for some platforms (Android, iOS, Windows 8 Metro) and needs to be specialized. On the other hand we are able to simplify the AddIn system when moving it to the PlatformSystem because we don't need a big AddIn system supporting all platforms with much conditional compiling.
THIS COMMIT DOES BREAK SOME FUNCTIONALITY. METRO DOESN'T WORK ANYMORE, AS IT IS NOT TESTED. DON'T USE THIS COMMIT IF YOU ARE NO ANX.FRAMEWORK DEVELOPER. We will catch up soon with a tested and working version.
