Moved player controlling to different resource.
Test refactoring.
1. Basemodel creation no longer throws unauthenticated exception. (this should be thrown in authentication inteceptor.)
2. Access-annotation now also hold information about how unauthnetication exception should be handled by inteceptor (either default redirect or error code return.)
3. Now playing-top part is now updated with ajax and is also updated every 5 seconds.
